Search Results: he ignores me when im at his house

Okay so this is very difficult to explain but I'm gonna try.
I meet this guy 3 years ago, I was 16/17 and he was 21, I know that it was wrong of course for the age, but I mean, we all make mistakes.
This guy he was rude, he was a player, a Fuckboy, I didn't knew that when I meet him, because well I moved from apartment and he used to live in the same place as me, he was my neighbor.
He just manipulated me, and well I really fell in love with him, we started to have like a sexual relationship it was weird, my mom never knew that of course, a lot of Shit happened in that time, this guy was just insanely weird, we have sex and then he turn like rude and he started to tell me hurtful words, so I just get tired of that situation and at the beginning i was depressed and everything because I just let him go, when I didn't talk to him anymore he used to go and knock my door, my window at 3 am, he even talk to my mom, it was a mess, but I never answer.
Okay so I moved to another city, and one day he just text me, I answer and he came to my house and we just "came back".. I was feeling like this time we really hangout and everything like a normal couple. But the worse part was coming, this guy used to work in a call center, so one day one of his friends tell me, "I need to talk to you" and I say ok fine, and he told me that this man fuck in the bathroom of the job a fat coworker lady, and that he gets fired, and the most hurtful was that when I say to him can I see you? He was like "ohhh babe I can't I'm working" and he really was fired... and I mean I don't gonna body shame because I'm not like that, but I was like.. really? He really fucks this lady? Wow.. and he said Im not finished yet, he fuck her too in my home..
and now he just came to my life again, and he want to see me and everything he texted me.. what should I do? Should I block him or ignore him?
