He’s been giving mixed signals as well, such as dressing fancy all of a sudden, staring at me a lot, sometimes being nice and other times rude. I get that he’s unstable (obviously) and he generally acts like this with people he’s attached to but it still makes me wonder if he would treat me this way if he actually did have feelings for me.
If they mistreat you before anything actually takes shape, it’ll be worse in a relationship. Some people are severely underdeveloped emotionally and don’t even know why they behave as they do. I was like this when I was young. It’s taken decades of therapy and working on myself to be emotionally healthy. Find another.
