I was so lonely I entered a relationship with someone I didn't love. It seemed like a good idea at the time.
Why did you enter a relationship with someone you didn't love?
I didn't want to be alone and ended up unhappy in the relationship. I had to change a lot in order to keep the person in my life.
While loneliness can be difficult to endure, you shouldn't try to resolve it by getting into a relationship with someone that you aren't compatible with. As you found out, it just leads to additional unhappiness and stress trying to change yourself to keep that person around. It's much better to remain lonely and wait for the right person to come along than be miserable in a relationship that you are only in because you're afraid to be alone.
It doesn't matter because I have a new girl interested in me, I'm moving on and never talking to that stupid bitch again.
While it's good to move on, it's unnecessary to call someone a name just because the relationship didn't work out. You said yourself that you weren't into them from the start, so it's not really fair to say negative things about the other person when you were just as much at fault.
