@DidIHurtYourFeelings: I get that his actions are making you feel a certain way, and that's something you're perfectly entitled to, but when you talk about it...make it about him.
Starting a conversation by telling him how he's hurting you is akin to saying he's doing something wrong. If you want him to open up he needs to be comfortable doing that, he needs to feel like you're listening to how he's feeling, and that you're interested in what it is that's going on in his head that is causing his ennui.
Reading this back it almost comes across like I'm saying *slap* "Hush woman! Your feelings don't matter, men are more important!" but I promise you my advice would be exactly the same if the gender roles were reversed.
