Maybe it is and I don't know it.
I used to see someone back in college days (in late 20s) we were never official and he was quite frankly horrible to me. I cut things off, and moved on with my life after being on/off with him for years and years and having enough of it never going anywhere. I really liked him.
Anyways, since then he has constantly been trying to message me. I've blocked him off multiple things and he finds my other social media accounts to try and send requests on. Worst case when he couldn't reach me he pretended to be a mutual friend and messaged me of his phone. Eventually I had to block said friend since despite telling him I wanted nothing to do with this guy, he kept trying to invite me out knowing this guy would be there and presumably set me up.
I felt so worn down with his persistence that I eventually (with dp's blessing) went to meet up with him to see what the hell he wanted. It was stupid I know. He very clearly wanted to see if the door was still open even though he knows I have a long term partner and DC. Whenever I questioned his motive he claimed it was innocent and would act oblivious to his constant attempts of communication.
He used to joke that we could both get married and yet still have something going. I thought this was a joke until now.
He's yet again messaged me, after I ignored a friend request on a inactive account that I don't even use.
I've told dp and he thinks nothing of it. But I feel worn down by his appearances in my life even if they are every so often. It's been nearly ten years of this. Surely this should count as some sort of harassment! When I've challenged him on this he says he just wants to be friends ect... Then admitted he did like me back then and just never said it. I really don't get his angle and how at this point he hasn't moved on with his life. I don't understand what he wants with me especially since we never dated. He is a very attractive guy and always had girls around him, so why me?!
