Is it normal i wont do this for my ex
So me and my ex of 4 years broke up but still spoke every day, after a few months of being broken up I had a sort of week long fling with this guy. My ex knows about it and we're kindof getting back together (its very complicated). He wants me to delete the guy I slept with off facebook, cuz sometimes he comes up in my feed when I'm at his house etc. He feels really strongly about it. I really love my ex, I want to make things work with him, but I just really dont want to delete this guy. If he'd deleted me after we slept togetherI'd have felt really shit and wonder what the hell I'd done to piss him off so much. I mean its like saying I cant even tolerate seeing his statuses once in a while. I don't talk to him but he was really nice to me and we parted amicably and I just feel it'd be so rude to delete him like that with him not knowing why, its not his fault he's in the middle of this stuff with my ex. is it normal that I wont delete him even though my ex feels so strongly about it? What should I do?
(I should add that I have done stuff like this for my ex before, for example this summer I got set up with a guy by my friend, he was a nice guy and really into me and he started messaging me on facebook, my ex got pissed off so I deleted him without explaining why, the guy was really upset and complained to my friend and i felt pretty bad about it)
