sidony, you make it sound like one has to like something, just because it is "good". I don't particular like lobster and I love lamb, something lots of other people don't care for. The relationship doesn't sound like it was for you. In your first post you said, "I screwed up a relationship that should have lasted" and I was struck by the "should". Relationships have no existance of their own, they're a construct based on what you and whomever wanted and you didn't want it and that's fine.

Do you have to leave your friends wholesale? Don't you have any close ones? Sounds like the group of friends is like the relationship, a "thing" you don't want now or that isn't working now and you feel it isn't worth keeping. There are individual people involved, not "relationships", "groups" of friends, etc. It's hard to differentiate between your new job, your relationship, and your friends. They all sound like the same sorts of "things".
