How do you deal with a man that doesn't talk it out?


I'm dating a guy... he's a very sweet person, a gentleman, he's respectful etc. But when it comes to the moments where he gets anxious or upset ( personally I choose not to add to the annoyance at the moment by saying much of anything, especially if I know I'm not the problem) but I'm the kind of person who likes

to talk it out afterwards... like go all Dr.phil on it and ask "and why does it make you feel that way?" But this guy just doesn't talk about it at all. The problem just kind of passes... i understand it.. a little... but how do I get this uneasy unfinished feeling out of me? I need to talk things out!
