My ex and I broke up eight months ago. We can't seem to talk without a fight occurring, so I personally don't see the point in talking. He broke up with me and refused to see me after we broke up. He didn't even have the decency to talk with me face to face. But lately, he wants to text me and that's it. When I brought up the idea of hanging out, he said that he's not sure that it's a good idea because I will "get upset." It really pissed me off because he just assumes everything. I am perfectly able to control any emotions or feelings I have and be civil with him. But for some reason, he thinks I'm still hung up on him. I found that I am much happier without him in my life. He was my first love so that's why whenever I'm sad, I think of him. I'm getting a new phone number soon and I was thinking about not giving it to him. That way, he will never text me again and I can move on with my life. He's always very indifferent and rude when I talk to him, but I always feel bad when I confront him about it. It's not healthy. Is this a good idea? Should I just disappear completely?
