Is it wrong for me to miss someone toxic?

There were some good times but in the end it ended because I knew he was toxic and he just didn’t really care for me anymore... he left me first and then when he tried to get me to go back to him I said no. Because I gave him way too many chances in the past and in the end it’s always the same it’s always my fault for everything and that I’m this and that. I still love him yes despite him being a toxic asshole but I made sure I don’t take him back. He has a restraining order and that way he is forced not to text me and me him. Sucks to love someone so much even though they never deserved any of it...
