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.
There are many people in the world. You don’t have to stay attached to this person if his behavior isn’t something you like. And it is ok to wait for a person to come along that treats you the way you would like to be treated (you deserve to be treated well). Best of luck!
