Bf trouble

Cal

A few weeks ago I let my insecure side get the best of me and after 1 and a half years I looked, for the first time, at my boyfriend's phone while he was asleep. I didn't do a full search through his phone I just looked at his blocked contacts on WhatsApp to see if he had blocked his meddling ex; which doesn't make it better I know. I felt terrible and I told him when he woke up, he was annoyed but we kissed and made up...or so I thought. Ever since then he keeps calling me "snoopy" and bringing it up despite knowing that I feel very guilty about it and at this stage it's upsetting me, especially because if I was to bring up any of his past blunders he would get annoyed and accuse me of guilt tripping him or use his favourite line "I'm not apologising for that again so drop it"

Should I grow up and take it on the chin? Or should I tell him to shut up? Should I bring up his past blunders? Or should I use his favourite line against him?

Sorry for the looong post but I just need to vent haha 😰
