My ex and I just broke up about a month ago. Well my bestfriend is still friends with him on Facebook. Well about a week ago I get a friend request on Facebook and it's from my ex boyfriend bestfriend/coworker. And then a couple days later my dad told me that my ex drove past our house which was also weird. And my bestfriend who is still friends with him on Facebook said that he still has the same profile picture that I took of him from my phone. Which I thought is weird too. Is is it me or am I'm overthinking things?
