Bad night, Bad life.

So I dated this guy for nearly three years, and when I went away to college, he abandoned me and never came to visit claiming he was “scared” to come into the city which is what led me to break it off with him. It has been nearly two years since I broke it off, and everyone in my life is still friends with him. It is like I can’t escape my past. My mom still considers him a son, and my brother thinks of him as a brother. A lot of my friends from home who only became friends with him because we dated are still hanging out with him even though they know I am not comfortable with it. Last night I receive a picture of one of my friends and my ex together pretty cozy, with no caption. And I also discover that my brother, whom I have been getting pretty close to, has been talking crap about me to my ex and he has been having a good laugh about it with my friends from home. Talk about a shitty night. When will I ever escape? Do I have the right to be upset about this? To demand that they cut off contact with him? I just feel so ignored and uncared for. What’s the point?
