Questions...

My husband is a paraplegic and I have a daughter from a relationship before him. He doesn't want to have sex and he says he can't we Dont try. I get rejected every time. I want a baby so bad. I want to get IVF. He said no. It won't be his. But its kinda the same with my daughter but he would be there from day one so what's the difference? He says marriage is the difference. He says no and don't talk about it. Said he won't stand by me if I decide to do this... Anyone go tho this? What should I do? I feel a hole inside me I want more kids so bad I dream if it all the time.
