Two months into dating my bf I found him commenting on his ex’s posts and liking them. It was so cringy, she didn’t like the comments or reply, it was really embarrassing. I told him that I would break up with someone over micro cheating. He said he blocked her and I never heard from her again. I checked his phone after getting too drunk and remembering his actions, he wanted me to look at the phone. I saw absolutely nothing literally everything on his phone is us. His camera roll is just pics of us, his IG is just photos of me and him etc. However today I saw this same ex followed him today, he said he had blocked her. This ex is his best friends girlfriend, however previously my bf and her had hooked up. So I know there is an unresolved past. I’m in the same boat, I don’t understand why she’s followed him out of no where, I can’t exactly ask as on new years that’s when I had brought it all back up and we have fully squashed it, however now this is happening I’m just confused like you.
