Just a thought. Isn't that illegal for a 23-year-old MAN to be having sex with a 15-year-old girl? You could report him. I know that might not help with your relationship with your sister, but it would be a way of getting rid of him. 

 Also, I realize you really love and care for your sister, but you also are responsible for your own kids as well. They have to come in first here. Not to mention your marriage. You need to be loving but firm with her and give her an ultimatum. 

Sorry if this isn't what you want to hear but get her to pack her bags and send her back to her mother. Just because your mum has a new job isn't any reason for her to put you in charge and raise her, because that's her job not yours. It is taking a toll on your family and it isn't your issue to deal with, it's your mother's issue to deal with. It's her daughter, not yours, send her back and let her deal with it. You're her sister not her mother and that's exactly why she isn't listening to you (in my opinion). Like Arna said, get facts, take photos, take notes and dob that boyfriend in. Oh how life is so unfair, her boyfriend is doing drugs and having sex (although it's actually rape) and she can't have house parties at a house that doesn't belong to her. She needs a reality check, show her the door and send her back to mummy. Mum can't hide from her responsibilities as a mum, regardless of what reason she moved for.

You poor thing!  Getting your household ripped apart in so many ways. Once a girl has desided that she is leaving all and having a sexual relatioship there is not much to be done. Sad but true.  You must wait for the awakening which usual happens after a child and going through sheer hell. So ...if  a heart to heart about where she see herself and what you expect for your sanity doesn't get through than Mom needs to come pick up problem child!  I feel for you as there is no good solution.  She is being selfish and so immature but then she is immature and is going out of her way to prove it. If she can not respect herself or your home than you have little choice. Best of Luck.

 Sometimes you have to be cruel to be kind....if your sister and her BF think they old enough to party, drink, take drugs (where are they getting the money) have sex ( which is illegal at her age 15)maybe they should be kicked out so they can learn some reality of living in the real world. I sense you won't do that but you and you husband deserve your life back and some peace and harmony returned. I feel your mother has to take responsiblitity back of her daughter, not you, this is not fair.

Pack her bags and send her back to Mum.

Keep us informedm I wish you well.

wow, looks like its best to just sit back and let her learn the hard way, theres only so much 1 can do. i can say a friend of mine was 19-20 and hes gfriend was 16 they had sex n had a child later they broke up ( 2kids later) but she took him to court and he got done for sleeping with a minor and was looking at 4-8 years prizon time. maybe u could go and see the police or a docs worker n ask for some advice on this 1 as she is only 15 and he is 23

i do wish u the best of luck i know it must be hard on you and expecially emotional side of things with hubby n yr sister.

ps- get a new lounge lol or go buy some sage and burn it threw out yr house get rid off all bad and negative energy

Pack her stuff up and move her out.  Tell her if she is old enough to be in a sexual relationship and to party, then she is old enough to take care of herself and pay her own way through the world.  I'm not kidding!!!!  She is a teenager.  Reverse psychology still works on teens!

As for the boyfriend and the police not being interested in the drug offences, they will have a field day with statutory rape charges- that is what is going on with your sister and her boyfriend.  Even though they are consenting to a sexual relationship, the law states that a 16 year old girl/boy isn't mature enough to make their own decisions on this, and with the boyfriend being so much older, it is even more concerning.  He more than likely has more than 1 girlfriend that is 16 or under.  If the police want evidence, you have a camera- its your house.

This is an impecably tough situation. It sounds like your doing your level best with a really rough situation. I can't really suggest anything, but thought I'd toss out a couple thoughts... I'm not sure how well they'd apply though.

What is the legal minimum age for consentual sex where you are? Most countries it's somewhere between 12 and 16 for girls, but the boys usually have to be within a certain number of years older than them. If it is more than that it's considered Statutory Rape, and he can be charged even if she consented. If your wanting to take strong action, this would be something to look into and at least talking to her about. Perphaps telling him he'll be charged would be enough to get him to break it off...

otherwise, if your really stuck...She is your mother's responcibility. You could always drop her off on your mother's doorstep! Though I'd make sure she was home first.

Sorry I can't be more help.

I Am's Child

i admire you for trying to be a mother figure for your sister but, you are not her mother and she is at a very vulnerable age.  she is rebelling and needs to be looked after by her mother. the fact that you have a child of your own indicates that you should try tough love.  tell your sister, if she doesn't stop seeing this guy and missing school, she will have to move out.  i know this sounds harsh but you have to think of your husband and your child first.  if your mother won't have her living with her, then try another relative who will have more influence on her.  she needs help now before things get worse.  she will eventually thank you.  good luck

 She's under 16, that's statutory rape. As her guardian you can report him to the police. I would also get your mother to come back and look after her- it is her responsibility, you shouldn't have to argue with your husband and have your own family in trouble to look after her. I hope it gets better soon.

She will hate you, and you might hate yourself but for her own sake, and your childs, she needs to move out of your house. You cant give her an option, she has to go.
You will need to contact your mother and tell her, and if she doesn't want her, ring a family member who might be able to take her in. In the very worst case, ring the CPS and get them involved.
Being 15, you can also ring child protection and tell them you need a rape kit performed on your 15 year old sister whom you believe has been in sexual contact with someone over 18 and he will be charged if it is found to have been correct. Which if you have witnessed it, it is.

Get hold of her mother there is only so much you can do for her. It sounds selfish but she is your mothers responsibility.  If she doest want to know contact child protection and get them involved they have the resources to and the experience to deal with her
