I quoted wrong because I wasn't super into this chick and I'm not too bummed that it didn't work out, just curious as to what you guys think might have happened.

Met this HB8 on POF. Talked for a few days through messages and then I got her number. Texted her a couple days later on a Tuesday and we went out for some drinks with one of her friends and two of my friends that night. This was not planned, we chatted for a bit and then she just asked if I wanted to grab drinks with her and a friend. One of my friends and her friend kind of dominated the conversation which I was fine with since it was a good time. I did find out she still lives with her ex since he's about to have surgery but he's moving out in a couple weeks, something I was cool with. However, she still hangs out with him all the time and they go out together a lot still.

She initiated texting both Wednesday and Thursday and then again, she asked if I wanted to get something to eat where her friend (the one from earlier) waitresses at. I had already made plans with some friends for later that night which she knew so I could only stick around for about an hour and a half. Anyways, we ate dinner and had a good time. I left, she texted me that night and then the next day. Then Friday night, nothing. I texted her Saturday (St. Patties) to ask her if she was downtown and got no response. She told me earlier that week that she was going out with the waitressing friend and her ex on St. Patties. I realize Monday that she defriended me on Facebook and haven't spoken to her since Friday.

Any idea what happened? Again, I don't care that much and have no desire to hang out with her again, just trying to learn from this.
