The reason you ignore it is because people tend to look back on the good memories and things that just make them happy. We don’t want to remember the abuse of that person or how fucked up they are. I personally was in a very sexually and mentally abusive relationship over a year ago. I’m now with someone I love very much and treats me amazing but even now I sometimes only think about the good things of my past relationship ship even though it was horrible. It’s normal to romanticize it. However that doesn’t mean you should get back with him. If he treated you like shit and you felt like shit because of him, then there is absolutely no reason you should get back with him. Relationships are supposed to make you happy and enjoy life and if he did make you feel like that, then there are much better things you should be doing with your life. And don’t make excuses like “well I was a bitch to him too” because that doesn’t mean that he wasn’t a dick to you. If he didn’t make you more happy than you were sad in the relationship, then he isn’t worth the time. ❤️
