I've been dating a girl for 2 months. It is the best relationship I've ever been in, she often tells me how great I am, how she loves me etc, but one thing's been bothering me ever since it happened.
Couple of weeks ago I went with her on a social event at my friend's house in order to have my friends meet her. I have one friend who is very charming, charismatic, really great with people, especially girls, they tend to really like him, even though he's not really physically attractive, so to say. He's short and bald, but really fun to be around, has some great moves and really has game. He has a girlfriend
My girlfriend is a bit shy but he made her laugh, he asked her various questions and she said at one point that she likes to massage people, me also, and then he asked her if she would massage him, that something's bothering him around the shoulder and she gave him a back rub. I didn't really like that, I felt a bit unsecure and jealous, but didn't want to appear needy and jealous so I said nothing. His girlfriend was around so he joked like my girlfriend should stop that his girlfriend is giving him a mean look. She later told me how my friends are great, a bit about each of them, but that everybody is a bit under the shadow of that one friend.
Last weekend we were at that friend's house again, played some board games, really had fun, played some drinking games which involved all kinds of different rules but it went great. We went out later for some drinks, dancing etc. and at one point that friend told to my girlfriend how she didn't gave him a backrub this time, and she told him that he should've made a rule that would include something like that. His reaction was like "damn, what was I thinking". It didn't bother me at the time but I started thinking about it and it's really bothering me.
I don't want to appear jealous, that guy's always been a good friend and I really like my new girlfriend but that thing doesn't leave my mind. Am I too insecure, should I talk to her about that ?
