A comment my boyfriend made has really triggered me and I don’t know why

[Luciferthethird]

I had a very long post written and then my phone died before i could post which says it all really

But the short version is I declined a girls trip because my boyfriend of 7 months had a weekend away planned, for reasons out of his control we had to postpone our weekend

Was I wrong to then go in the girls trip, ( that he assured me he was fine with me going, no problem at all and there would be no resentment) when I came home told me he felt I’d “made the wrong choice” and I should have chosen to spend the weekend with him and that he feels like he comes second.
He doesn’t but I also don’t want to put friends and family aside because I’m now in a relationship
its the made the wrong choice comment it triggers me and I don’t know why I felt like I was being gaslit buts not gaslighting or is it… I don’t know everything else is hunky dory i just can’t seem to get past this

Hang on, have I got this right? You were only away one night, coming back on the Sunday. Which is when you would have gone away with him if he hadn't had to work. And he had his children with him for the weekend? Is that right? Are you sure he didn't just want free childcare?
Is he this upset about one flipping Saturday night?
Be very, very careful. Please.

And if I were you I'd be planning a lot more nights out with the girls.

'I’m not going to break up with him, I think he was genuinely upset I decided to leave him alone for the weekend.'

Yeah, that's the problem. He's no business being upset with you for living your life.

Agree with @MeinKraft

..be careful with excusing manipulative/controlling/ possessive behaviour with the reasoning “he does it because he loves me”

He upset you and deliberately made you feel guilty because he missed you, because he cares about you? 🤨

You’ll be tying yourself in knots next time you’re invited on a girls night away because you know how he’ll react.
