<human>: First off, I'm sort of an introvert and I don't get out enough so it's hard for me to make friends. A couple years ago I met my friend Brett [26 M] and we got pretty close. We both had a lot in common and I was excited to have him as a friend. About a year after that he met this girl Susan [23 F] and they became good friends. Shortly after that, he ended up kind of hooking me up with her. So far, so good.

The problem is, now I am with Susan, and Brett is closer to her than he is to me! I'm actually kind of jealous and annoyed but not in the usual way. I'm friend-jealous! For instance, when he wants to hang out, most of the time he will text her first and then she will invite me along afterwards. I almost don't want to hang out with him anymore. Just to be clear, I think there's near zero chance of anything weird going on between them, I just don't like "sharing" my friend.

I feel somewhat ridiculous about this, because I don't feel like anyone has done anything wrong. For me, it's just no fun being friends with a guy who's so close to my girlfriend. I can't have a "guy's night out" because he always invites her, and even if he doesn't I can't talk about my relationship with her. I've had friends drift away before and that can be painful but I'm ok with that. But this situation, while not the end of the world, just constantly annoys me.

I don't feel like I can talk to my friend or my girlfriend about this without it being weird. In fact, I kind of feel like a petty dick that I just can't let this go. It's just a really weird situation for me, because I've been in a lot of relationships and I've never had anything like this happen before. I'm curious if anyone else has experienced anything like this or has some advice on how to handle it.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My good friend is so close to my girlfriend that it bothers me, in a "friend-jealousy" kind of way.
