I want to start TTC

Ok so I’m ready to TTC again, I have been for over a year. My husband just won’t hear it though. I’ve been bringing it up causally ever since I felt ready and he gets so defensive about it. Of course I don’t want him to feel pressured but he won’t tell me at all when he might want to start trying for our 2nd. It just feels so hard because I want this so badly and idk what to do. The desire for another is just so strong now and I’m not sure how to bring this up without feeling like I’m nagging. I’m worried we’re in such different places about it and its so hard
