Aawww.
Well that stinks. I'm sorry.
I ended a 12 year relationship awhile back, but under different circumstances (I had grown very tired of him, and he couldn't hold a job). But still, it was hard the first few months not to have him around. I cried every day for weeks, and I barely even liked him anymore. No comparison to your situation, I know, but breaking up is hard to do. A tired cliche', but so very true.
I hope that you'll feel better soon. You were very brave to end it, painful as it might be. You'll be better off in the long run if what you needed is something he can't give.
Here's another cliche' for you: Time really does heal all wounds. You'll be okay. Poor baby.
Hoist a few with LittleK tonight; I suspect she's got a strong shoulder for you.
