So i’ll start off with this my boyfriends bday is 30th march and this girl wished him happy bday, they have a past together but they weren’t in a rship, they both had feelings so i’m not sure why it never turnt into a rship . He told me on like the 2nd April about it and I was fine with that but I was confused why he didn’t just tell me as soon as it happened. Obviously we have been in lockdown and we haven’t seen each other in couple months but then we finally were allowed to meet up, on the day we met up it was like end of May and he let me go on his phone to change his lock screen so as i was going through his photos I seen a screenshot of him and this girl snap chatting, it was just something about her having to take tablets for anxiety and sleeping, I might be over reacting but i’m really annoyed about this just purely based on the fact that they have had a past and she was obessed with him. He told me that they had been chatting on and off since his bday and the screenshot were from 15th April so they had been talking for around 2 weeks and he didn’t think to tell me because he felt it was not important. We talked about it multiple times at the end of May but I just really can’t get it out of my head. I may be insecure because I was cheated on in my last rship but I really don’t know what to do because he gets annoyed when I bring it up now and won’t speak to me about it. Pretty please can someone help me with this!!
