You know that saying "Better to have loved and lost than never to have loved before?" Easier said than to live. I prefer "Better to have loved and won than to have lost in the first place, and now: champagne, karaoke renditions of "Heart" songs, and a hot shower for two."
It doesn't roll off the tongue, but I like it. However, that doesn't mean the first saying isn't true. Love is like that last slice of pecan pie you ate and "regretted." You didn't really regret it. That slice might have added a pound. or upset your stomach. But at no point are you ever sincerely angry or disapointed at enjoying such a wedge. Of course, pie doesn't make you feel like a dandelion puff floating along with the wind. Love does.
I'm sorry you lost what you thought was love.
The best way I know how to move on is to pretend to move on, and hope that, eventually, one day, you'll wake up and realize you actually have moved on. You handled it perfectly when he talked to you. You were polite. You didn't turn into a human fire hose. There was no begging. No fires were set. More importantly, you didn't make him pay a price for not feeling the exact way you feel. Hopefully, you didn't talk for long, and were able to hurry up the awkward situation.
If you're still hurting, I say pretending to be "over" him is good enough. You can tell your friends you've moved on to stop them from asking. You can pretend to have moved on, and go out on dates, and who knows? Maybe you'll meet someone who doesn't totally suck. I promise you, though, that if you act like you're okay, the rest of you will catch up.
This doesn't mean that on the occasional Saturday night, you can't do your best couch cushion impersonation, or eat an extra slice of pecan pie.
