I have a confession, I acted like a big bitch to my LTR.

She had told me a dude from her gym had followed her on IG, liked photos of her, then she followed back. No mention of reciprocation of liking pics. (Yes its stupid as fuck. After writing that out I feel even worse now). I then said to her "shoulda hit him up" we laughed it off, but it got to me. I proceeded to be distant throughout the night, then later told her it annoyed me. We spoke about it, she seemed to understand why i was annoyed. But nonetheless I shouldn't have let it bother me or let her know it bothered me.

This is the first time in the few months I have acted like this, and it was out of character. In times of acting like this, what's the next best course of action? Just pretend nothing happened and proceed as usual?

Roast me though fellas, I deserve it.
