I saw a picture of my girlfriend and my friend...
..and he had his arm around her. I'm not really a physically affectionate person, so this really made me jealous. Is this normal, or at least reasonable? Should I mention it, or let it slide? If I should mention it before it becomes an issue, how should I go about it? I admit that I'm naturally jealous, and I don't want to be, but I am.
Background: They're off together studying abroad for a year, so I check up on their pictures on myspace.
It's not that I think she's cheating on me, or that I don't trust her; it's more of the fact that, my friend is ALREADY getting to spend a year with her (they're together almost all the time since they're the only exchange students there), and it'll be months before I get to visit... so it sucks that they're physically close/intimate now.
