Okay. Recently, we were at a club and met this group of people. My gf started having a chat to one of the guys. He was clearly into her and hitting on her. We were all having fun and got eachother’s instagrams. We saw him again the next weekend at the same place and a few days later I started to have this feeling that I should be suspicious. I (regrettably) looked on her instagram to find that she has made a close friends story with just him in it and posts daily little stories and videos about her day and fit checks and other problems (ones that she hasn’t even told me about. I spoke to her saying that I didn’t like that she talks to him but did not mention anything about the fact that I went on her phone. She reassured me and promised to stop talking to him and the next day I regrettably looked again and she is still posting and talking to him. What the actual F\*\*\* do I do about this?
