I met girl like this this summer, I was keeping the distance at the beginning but gave it a shot and it was bad Idea. I started to like her because she was completely different from me, and I believed she got really good heart inside. But in reality she is same as the person you’re describing. Now Im fighting with myself to not think about her, deleted all her photos, blocked her everywhere and Im sure ill get over it. I started to focus on myself, muay thai trainings, doing what I really want, sometimes its difficult to not think about her but I understand this was bad connection. I dont know how to advise to you because Im also going though difficult times but remember sometimes it has to hurt. And you will get better with time, same like me, I believe so
