Why do I still think of my ex and miss him even though I know he wasn’t right for me?

Hey y’all, 4 months post break up after a 4 year relationship. I specifically asked him for no contact so I can heal to avoid unnecessary breadcrumb texts. These last months have been crazy and quite a transition, but I slowly feel like I’m getting to where I’m supposed to be. Today is my birthday, And leading up to my birthday, I have been thinking about my ex constantly I find myself missing him at times and wondering what he’s doing or how he’s been. I hate these thoughts because I know he didn’t deserve me and he didn’t treat me with the same respect and love I treated him. I try to remind myself that these past birthday that I had with him were never that special And he always made me feel like I was a burden so I know all these things. I know he wasn’t a good guy to me, but yet I have these feelings where I think about him wondering if he’ll text me on my birthday and kind of missing him. These last couple months, I’ve been doing everything right I’ve been working out, focusing on myself doing therapy surrounding myself with amazing friends who make me feel great. I hate to even have these thoughts. I miss somebody who wouldn’t have even made me feel that way in a million years. Any advice moving forward?
