When you say he's not interested in intimacy or showing passion... I honestly almost feel like that shouldn't matter. Because you two are a team, and you are interested in those things. Just like you show interest in his business because it's his and you love him. Relationships are about give and take. He has to be willing to meet you half way, and you have to be able to discuss these things together.

I also agree that maybe you need to try to build up to it again. Plan date nights. Start with someone casual once a week and build up to more fancy, romantic nights. Ask him to plan every other one, or maybe just once a month till he gets into it. And dont expect the night to end up in bed, just see where it takes you.

I definitely understand what you're dealing with. My husband has never been very sex-enthused due to an ex girlfriend, and things only got worse when he was in a really stressful, really self-esteem killing job. And we used to fight a lot about it because I didn't want to always have to put myself out there and get rejected a good portion of the time. It hurts, darn it! And honestly, the only thing that REALLY worked? Lots of communication (and then follow through on his part), and eventually a new job... I'm sorry I don't have better advice, and I know how awful this... But start talking to him.

Good luck, we're here for you!
