He’s one of my best friends and when it’s just him and I or me, him and pretty much anyone else hanging out he’s fine, but when his girlfriend hangs out with us he acts really obnoxious and does a lot of things that make me uncomfortable. I’m worried this might lead him to believe that I don’t like his girlfriend since when she’s hanging out with us I usually cut out early. It’s not that I don’t like his girlfriend ether, her and I get along really well, it’s just that when she’s around he acts so differently and I have a really limited capacity for tolerating him when he’s acting that way.
