That was the first thing I wondered: if I said something to make him think this. But I asked him about it and he said it's just an irrational fear that he feels is getting worse the closer we get to the u/s. We'd been trying for 2 years and I think he didn't really believe it was ever going to happen... I don't know if this could contribute.
It could be the other extreme he not care at all about you... My husband was like that with our first child and I know it is annoying but he calmed down and I am grateful to have such a loving caring husband especially when I read some people posts on here bout cheating bf or spouses that are mean.
I was thinking that same thing...it's a bit odd that he's so paranoid and pushing the issue so much. My first thought is that he feels guilty about something or he's insecure for some reason or another. Try talking to him and see if that resolves the issue.
Just tell him that right now your hormones are out if control but for him to stop questioning you about you leaving him. Just weird that he keeps bringing that up to you did you mention any time that to him? For him to think that? Well good luck And be patient with your husband
