Why do some guys keep coming back?

Anonymous
I was friends with benefits with this guys almost two years ago which ended pretty badly, I developed feelings and he claimed he did too but would play games with me. However, last summer he reached out of nowhere and one thing led to another and we ended up sleeping together one last time. I cut him off immediately afterwards and he got mad but I blocked him and moved on. I’m now in a relationship and he reached out once again out of the blue. Out of respect for my boyfriend I didn’t entertain it but it’s been on my mind. Admittedly, I’d forgotten about him and thought he did the same. Odd thing is, I blocked his past profile and he created a new one. Claiming that his other one got banned, and this isn’t the first time he’s done this. I probably shouldn’t think on it too much because I am happy in my relationship, I just can’t help but wonder.
