<human>: So about a month ago I (21/f) met this guy (26/m). We got on good quickly and started dating - despite the fact that in October I am moving from Europe to the US for 2 years.

We've talked about this, LDR is out of the picture, he doesn't want that kind of commitment. We're just using our last time together to have as much of a good time as we can, then we'll see what happens - possibly stay online friends, but definitly not 'be together'.

I know he's right - it wouldn't work out, and chances are it wouldn't have worked out in the long run if I had stayed here either.

So now I'm moving away in less than two weeks and I have this awful separation anxiety. He's been so good to me and I haven't felt like this for a long time. Rationally, I know this is all for the best and I'm going to get a new life over there and whatnot, but emotionally I'm devastated right now.

I need help on how to cope with this, how to reframe it so even my emotions can agree. It's really just an issue of getting over a crush I don't know all that well anyway, but I haven't felt like this since my teens so I really don't know any good ways to deal with it.

Love all of ya guys.
