Well that doesn't really make any sense to me and seems to be counter productive thinking. We were in a relationship when she moved. Why would I think just because she moved she'd fuck someone else? That would have been cheating and thinking about that sure would'nt have helped me. I did'nt think about or attempt to have sex with anyone because she was gone. We had trust in each other.
And while you will say you weren't in a relationship for the last couple of weeks, I didnt think she'd do that so quickly or right now as she said it wasn't going to happen and to not worry. Ok well I was wrong, but my point is really before this I'm not sure why I should have expected her to fuck other people. That doesn't seem like a healthy outlook.
You say don't become bitter, but the lesson here seems to be don't trust people and become bitter. So what is it? In plenty of relationships theres probably going to be plenty of time where you're not together, am I just supposed to expect because I'm not in the immediate area my partner is going to fuck someone? Should I hover around my next partner? I don't get the lesson here beyond never attempt a long distant relationship which doesn't seem to be a positive lesson. I mean yeah I'm not going to try that again, but still.
