I could be wrong but it sounds like you arent looking for something to be wrong. It sounds like you are feeling him become emotionally distant and are trying to provoke the intimacy you once felt. I think of it more as an emotional guessing game. When you feel him pull away you freak out and do something to test the emotional waters between the two of you. And im going to guess you're a little irritated and threatened by his new seriousness. It's very much an emotional yo-yo. After all that you've been through with him, and previous experiences, it seems you've become a little too emotionally dependent on him. To help calm your anxiety you might try claiming some emotional independence by being more curious of who he's becoming rather then thinking about how his mood swings are effecting you. And you might want to do some reading on the subject of codependency.
