My boyfriend of a year told me that one of his exes reached out to him a few weeks ago for a booty call, to which he replied he has a girlfriend so no. He only told me about it last week because he said he didn’t want me overthinking. Anyway, I let it go, it didn’t bother me. Then I see that she followed him on Instagram and he followed her back, I didn’t say anything to him about it. He then unfollowed her earlier this week. Today I go on my instagram and she’s at the top of my searches from last week and see she posted a new pic, a selfie. I go on it and he liked it. She posted it today, 8h ago. So he obviously went out looking for her profile since he unfollowed her and liked her fucking selfie she posted today. I didn’t say anything about it but it pissed me off, like why do you have to do this shit? Am I overreacting?
