You do need to get your needs heard. If he won't listen to you maybe you could write him a letter explaining everything you need from him. I would then give him the letter to read while you go out and not mention it for a couple of days.

Hopefully he'll start talking about it himself.

Try to make the letter positive, none threatening and don't blame or shame him. Just tell him what you need from the relationship and where you hope the relationship will go in the future. Also it's good to try to explain why you need these things, if you can.

Hi,

It seems that you are in a bit of a tricky situation as what you were promised in the beginning has now changed.  I do believe that the more pressure you put onto your bf the further you will push him away.  No guy likes to be pressured into getting married and they need to do it on their own accord when they feel the time is right.  Apart from having the ring on your finger are you happy with your relationship?  If the answer is yes then don't stress about things as you may spoil it by putting pressure on him.  If the answer is NO then you really need to do some serious thinking as to whether you want to be in the relationship or not.  Don't bring another child into the world if you are questioning your relationship with this man. 

You have the right to have the answers to your questions but you need to pick the right time to talk to your boyfriend.  So why not say something like....babe I have a few things that I need to talk to you about when you are ready to talk I would appreciate you come and get me.  That way you know that when he does come and seek you he is in the mood to chat.  Think about the questions you want to ask him before you do have the chat that way you are clear with what you want to ask and as much as possible try and stay on the topic. 

I wish you the best of luck

Yes, you DO deserve to be happy!!   It sounds to me like he wanted to "try things out" without making it permanent and may now be having reservations about going through with it.  Whereas when you are married first, you have already made the commitment.  Be glad you haven't married him.  You deserve an answer to your questions, and if you want to have more children, find someone else.  Imagine what life would be like if you were to get pregnant with another child by him?  Would he just leave you?  Something to think about...

Take care!

Very sorry to hear about your situation.  These things are always really difficult to deal with.  Whatever you decide to do, make sure that you have a great support system, anyone that will lend a shoulder and an ear;  No one should go through something like this alone.  Everything I have to say is just something I would do in the situation, just advice, so please, do what feels right for you.  First off, you need to be honest with your boyfriend and honest with yourself about your expectations.  Don't go into it thinking that everything is going to work out like a fairytale or something.  He is being very unfair to you because he's obviously not being honest with you.  Tell him exactly what you want, even if it would pressure him.  If he doesn't share the same idea of your future together one of you is always going to be disappointed and that is no way to live especially with your daughter.  If he doesn't want to get married and you do your both going to have to face some hard truths. Some people don't want to get married, and that's fine, but they are usually with someone who also doesn't want to get married.  If you really do, that's never going to change.  Now, you say, he doesn't even want to have more children.  It sounds to me like he may be feeling trapped, like he doesn't want to add anymore responsibility to his pile, to have more people caught in the crossfire, if you will, if and when he decides to jump ship.  You need to come to the very difficult but very real possibility of him leaving, even if it's just so he can pleasantly surprise you.  I don't know the full story and all that I've said could possibly not even apply to you, but my short answer (could you imagine I could be concise??!!) would be honesty.   I wish you all the best of luck and all the happiness in the world.  You deserve to be happy.
