I've been in similar situations with my husband many times, so I can relate to what you're going through! For now, it's probably better to just not do anything else and either wait for him to open up or accept the fact that he'd rather not deal with the issues the two of you are having.

Some men are just not very open by nature. When men have a problem, they tend to close up until they feel like they can solve whatever problem they are dealing with. Unfortunately, he might not care enough about the things that you do to do anything about it.

What Adam said pretty much hit the nail on the head. Some people would rather avoid problems rather than deal with them directly. As for the intimacy issue, it's possible that he might be having some male difficulties that he's to embarrassed to talk about?

Also, if he's been really stressed out because of work or other things, that could also cause some people to not want sex as much. Just step back for now and if he doesn't come around, then there isn't anything more that you can do. Sorry to say that, but it's true. You did all that you could do it seems like.
