So... I'm talking to this guy that I had an on-again-off-again association with. We never officially dated, and ended up losing connection. But yesterday I went to a party and saw him. We all got drunk and just talked and it was nice. He messaged me today and the conversation was kinda boring. Like, it didn't flow like it usually did with us. I feel like I screwed up my chances because it was such a lousy conversation... has anyone ever felt like this? Also, could you maybe give some advice?
