How to talk to your S.O.

Me and my husband can't get pregnant. We've done everything possible. Besides the fertility that costs $1,000-$30,000. My husband "says" he cries when I don't get pregnant. I don't know how to talk to him. Every time I bring up trying something new he just agrees and says sure or yes. But never gives me any input.

I don't know if he's doing it because he thinks I want him too. I need advice. I have no one to talk to so you ladies are my last hope. It's my fault I can't get pregnant. We had him checked and it's all me. I don't know what to do. I could make my self better. But I work and go to school.. how am I suppose to loose weight that's a huge commitment. And I smoke which makes it 10 times worse. Been ttc for 2 1/2 years and been smoking 5 years. I can't keep smoking and I can't keep being the weight I am. Help is much needed and opinion too.
