You say that you are confident when your mum and husband aren't around- do you feel undermined by them?
Could you SAY what you want from them? in other words, take control of your life again?
For instance, don't allow your mum to come and visit you- and make you feel angry- if you don't want her to- she doesn't have a right to walk into your home! Being a mum puts our own mother/daughter relationship into the spotlight- you need to get that resolved,with counselling, of at least along, honest talk with your mum- on your terms, at the time you choose, at the place you choose. Be the adult- and say you want to talk to her and that the past has to be put behind- and that your relationship can carry on- but only if you both agree to changes.
Don't have people in your life you make you feel bad- either cut them out, or only carry on the relationship on your terms.
Your husband- ask yourself:
Why did you marry him? You were together for a LONG time before you married- did you marry 'cos it seemed the next step? Or you were afraid to be on your own? Did conversation flow then?
what's changed?
can you get back to what was good?
When you say that you don't kiss, are you rejecting him, or are you waiting for him to make the moves? Ditto the conversation - are you offering anything in terms of conversation?
Has it occurred to you that he might feel isolated too as a result of the baby and that you seem to be completely pre-occupied with how YOU feel- and not how he might feel?
I think you need to be honest and ask if the relationship was ever any good- and if it was, how can you make it better. Or- was it a mistake- and now you feel tied with the baby and the shortcomings of this man in your eyes, has really hit home, as you ar enow a family- and you can't walk away as if you were on your own.
Be honest with yourself. Seek help to do with your Mum- you've got a lot of emotions to work through.
