I really feel for you sweety. My mother in law is similar. She believes that it is her duty to tell me that I dont know how to look after my own son.She lives in Scottland, and me in Australia, she hasnt even met him yet, but she stiil thinks she can do a better job of raising my son.

Sometimes i see a bit of her in my partner, but thankfully all i have to do is oint it out to him and he stops it.

You should do what you believe is best for you and your son, they dont call it mothers instinct for nothing. And you never know, leaving him for a while might be what he needs to realise that he is doing something wrong and fix it.

Keep your head up sweety, and remember that pain doesnt last forever.

I can't help, but relate.  My inlaws are a constant source of problems and we even live halfway across the US from each other!  They are always undermining me and talking disrespectfully about me to my husband.  He detests it and it has drove them apart.  Since having my daughter they feel like they have a right to see me whenever I am in town to visit my parents.  I understand this, but I can't stomach them.  I still allow them to spend time with her.  The minute they speak ill of me to my child, it's done for them. 

They are the type that are too busy to come and visit us, but want us to cater to their schedule when we visit our home state.  Annoying, but I am blessed to not live closely to them.  I just pray and pray to be the strong silent one and not stir up trouble.  As long as my husband stays on my side and we raise our child the way we want, their words will never have power over us.  The moment I start letting it get to that point, they have won. 

Your family (husband, children) are more important that petty words.  It is what I remind myself constantly when my father in law tries to stir strife.

I dont see much of my in laws as they live in Europe and me in Australia but I am glad in a way that we are so apart and can be civil to each other because if I was to live ther I dont know how long I would last simply because we are so different and when we go there my husband starts acting like them and that gets on my nerves big time. But at least he knows what he is doing and understands that I dont like it and is my rock in that see of strangers because that is what they are to me. I have seen them total of some 50 days in my life.

The problem that you have is what my cousin has. Her in laws started to interfear a lot and her husband is the bigest mummy boy there ever was. They wanted to sell the house and move in with my cousin and with the money they got from the house to enjoy them selfs. My cousin said no. And he said they move in or I move out and the idiot left living her with 2 small kids. well if you ask me she is better of without a man like that.
