To be honest, I am not interested in being friends with a person when I get sidelined the moment someone goes into the next relationship. I have better things to do than to revolve around someone else life. I have my own friends. It's a very frustrating experience because you try to stay in touch and you don't know what's going on. It's not your fault.
I try to balance my relationship and my own, personal life. Breakups happened and rougher times in a relationship happen and it's essential to have your own friends. It is very important to me to not give up my identity and my social life. But it has to be said I also don't really accept too much inference into my own life and I don't think I could be in a relationship where each one doesn't have their own space. I know relationship that wouldn't really work for me because you have to negotiate stuff that is not negotiable for me.
