Emotionally abusive ex boyfriend visiting my parents!?!?

UPDATE: It’s been awhile since I posted this so idon’t know if any of y’all will see this. Today my ex showed up to my parents house and told them he wants to buy the house off of them if it goes up for sale next year. I’m extremely uncomfortable. Wtf do I do.

So my ex boyfriend I dated for 1 year and ten months has not gotten out of my life for the past two years we haven't been dating. I have been dating someone new for almost the sum of that time and he just won't leave. We have every issue in the book and our relationship had strong signs of emotional Abuse, he was very controlling and manipulative, constantly pushed me down and convinced me he was better than me for basically everything. Sometimes he would cross sexual boundaries as well and not respect me when I told him something would hurt during sex and that i didn't like it. He would just say "it's alright I'm almost done soon" and keep going. my parents know he was controlling and manipulative and my mom is the one that was constantly telling me our relationship was sick (regardless though they did get along she just didn't agree with me being with him even if she felt for him because he has lots of issues with his mother) so she took him in while we were dating and he lived with us for awhile. But now irregardless I've been trying to get him out of my life for two years . He's come into my work on multiple account, messaged me to "send my parents on a vacation" he never did. Because it was about getting to me and not to them (they don't understand that though) but now I am absolutely furious because 2 YEARS later he drives all the way to my home (an hour from where he is) to stop in at my parents. My parents don't understand why it bothers me. But I've worked super hard to obtain my mental health and him being around my life makes it extremely hard. I've told them that but my mom just feels bad for him. He lied to her on this visit saying he takes care of his brother when really I know for a fact his brother lives with his dad. He's just pulling a sympathy card. I just don't know what to do anymore. They wouldn't invite him to dinner if he punched me in the face, but he was emotionally abusive and it's absolutely fine? I'm at my wits end. My mom thinks I'm the one being out of line and my head is in the wrong place but I just don't understand how a mom can sit down with her daughters emotional abuser and just say that she's acting irrationally and stick up for him and empathize with him. I don't feel any support.

I just wanted to know what all of my eve ladies think of this situation!
