Pearl, WOW! Going to a bar, and not saying a word is probably a great idea.
Not to rain on the parade - but a couple of thoughts:
1. You just said in a recent post that you wouldn't take xBF back. Did you mean that? Or was it just steeling your spine?
2. I wouldn't respond until Sunday. Maybe confirm receipt, I dunno, but I would absolutely sleep on it for a couple of days. I would also let xBF sleep on it - make sure he's not just waxing nostalgic, and giving you false hopes.
Remember the rule - don't believe what they say! That works both ways...
My goal here is not to dampen your spirits if you're excited, but rather not wanting to see you be hurt.
