This girl I was interested in a few months ago came on messenger and started talking to me all sweet, "Hey baby", etc. like she was hot for me. She's made it pretty clear before that she's really not interested in me. At first I didn't even think it was really her, but I did a couple things to corroborate and it was. Alarm bells going off- she was coming on too heavy, and it was out of character, but I played along on the off-chance that she really was serious and not leading me on. Still, I kept myself emotionally detached. I was right; she was playing games with me. The let-down was small because I hadn't trusted it, but still... Why do girls do that?
