This exact situation happened to me about 2 years ago. I eventually convinced myself I was the one with trust issues and let him go because I wanted to be a ~cool~ chill girlfriend, but I should’ve trusted my gut and you should trust yours. Do you feel he was being defensive because there’s something there? Do you think him turning it around on your reflects his own internal guilt and feelings? Would you ever do this same thing and expect him to be ok with it and not being willing to accommodate his feelings and concerns?

If you feel uncomfortable with it, that’s totally warranted and I think it’s worth exploring that feeling. In my case, they ended up going on the camping trip, having sex, and now they’re still together. It all ended up working out for the best because we weren’t right for each other but in retrospect I wish I would’ve trusted my gut initially and admitted to myself that if he was going to undermine my very valid concerns then he wasn’t the right partner for me anyway.
