My boyfriend is a very social guy and works at a restaurant where everybody gets along really well. Often they go to a bar after work and have a few drinks. The other night among the other coworkers was a girl who he thinks is really cool (she is happily engaged to a guy who my boyfriend is actually kind of friends with). Apparently they were having a great time and she mentioned how she has two tickets to an art museum and asked if he wanted to go. Being an artist, and thinking this girl is nice, he wants to go with her and asked me if it would be ok. On the one hand it makes me super mad, why can't he make friends with a guy? He knows that I'm definitely a jealous type and get uncomfortable with him having connections with other girls, and it drives me insane thinking of them talking and laughing together, having a grand old time. But then I wonder if I'm being immature, I really believe him that he's not attracted to her, and that he really loves me, and she really loves her fiance. He says I'm ridiculous for expecting him to never have any sort of relationship with a human that has a vagina again. But I just think it's inappropriate for him to go spend quality time getting to know this other female. It almost seems like a date to me... Is this situation like nobody is right or wrong because it's different for everyone, or am I completely right or wrong? Please let me know what you think!
