Confused on how to approach this situation

So my husband and I talked about adopting a baby in the beginning of our relationship. We got married and we talked about kids again and he now wanted to foster v.s adopt. As I have gone through therapy for myself I realized as my friends and family get pregnant I want that. (I had a miscarriage in 2016 and my husband knows) after I expressed to him I wanted a baby he said okay we need to get tested to make sure we can. That was almost a year ago and we still haven't gone to the doc. He was away for work for 3 weeks and I guess he made his mind up. I get to the ceremony for his work and I'm sitting with my husband's friend "A". She mentions how sweet it is that we are going to foster. I said what? And "A" said yes it's amazing you and your husband are going to foster! I said oh no, we are trying for a baby. And she got quiet. Then she walked over to her husband and talked. Then she came back and mentioned it again saying my husband has been telling everyone that we are going to foster and how special it is, and that my husband has been talking about it. I'm confused and hurt. I love that families can foster but I want a baby, I want to feel that bond. I didn't get that bond after I lost a child. I also understand that fostering is to reunite the families if they can and I do know some kids age out. It's horrible. And I'm so confused on how to approach this with my husband. I feel like this is almost grounds for divorce? Am I crazy!?
