Having sex while unconscious?

So my fiancé lives out of state from near the moment for his job. So we visit eachother every few months, this last month I stayed with him and his family for about a week. During that time, we decided to have some fun and make a bonfire with some of his friends, we where drinking. After his friends left my fiancé and me went to sleep. I remember going to sleep wearing shorts and a shirt, and the next morning I woke up without any clothes on. I asked my fiancé what happened since I didn't remember. (Normally if I'm drinking I don't remember much) he said he didn't remember anything either: so fast forward a month and he told me he wasn't honest about that night. He said he had sex with me and I wasn't contious because I was drunk. He said he came in me on purpose ( we both want children , but we agreed to wait until after college, although if it happened we would have both been happy) because of that I wasn't too concerned about it, because it's something we have talked about anyway. It just bugs me because if he came up to me honestly and told me he wanted to start trying now i would have said yes, instead here I am confused as to what he wants. I'm not sure how to handle this, if I ask him if he wants to start trying, he will say no, yet he does something like that without telling me?
