Social interactions

Lately I have been wondering a lot about how relationship work and about why we have a lingering feeling to have certain people in our lives eventhough everyone tells us to forget about them.

Relationship (this includes friendships) work in strange ways. But what do we do when things don't go the way we want or expect within that relationship?

For example: I was having a really difficult time a few months ago with a very difficult and delicate situation. Someone I love and whom I thought be my friend, told me that they cared about me a lot and that they would be there for me..... I think you can guess what happened next.... I was tossed aside, completely ignored, not spoken to, up to this day I still haven't seen or spoken to this person..... And I couldn't feel more stupid about believing this person, that I trusted them. Now, I can't tell you what happened or what the situation was, but I think everyone will have experienced something along these lines. But when do we say enought is enough?

My other 'real' friends and family have been telling me that I just need to let this person go, that they are not worthy of me. Part of me knows they're right, but I just feel like I can't let go and don't want to. Yeah, I've been treated like shit, but I'm still willing to look past that.... I didn't expect that things would go this way and I've been going back and forth about what to do and how to handle the situation, and I just can't seem to figure it out.

Which leads me back to the big question: when is enough enough? When do we pull the plug out of a relationship and move on? Can we move on? How do we let go or do we all keep lingering and holding on to relationships that went wrong? And if we do keep holding on, what are we holding on to: the relationship, the person we were in the relationship with or the memories?

I've been stuck in this rut about what to do and about how I want the relationship with this person to go in the future. That is, if there will be a relationship in the future. I've got so many questions and no one really seems to know the answer. They'll tell me the standard things, but it doesn't get me anywhere. I just keep coming back to 'what should I do?', but mostly I'm thinking: When is enough ENOUGH?
