The other night I was out with my friends when I unexpectedly saw my ex and his friends, I was pretty tipsy and caught quite off guard but when we bumped into each other we said hello etc.

I can’t remember every detail but I am worried that I acted rude or standoffish as I didn’t really properly talk to him (we were in a club tho so a little bit hard) I still really care about him but I feel the way I acted suggests to him that I dislike him... he wasn’t really chatty with me either and it felt a bit awkward, does this mean he doesn’t care about me anymore? Or could he still care... part of me really wants to message him to tell him this but I know that would be a mistake

Later in the night I saw him a few times but we didn’t talk again... is that weird?

Any advice would be so helpful
