Girl who has a boyfriend shows a lot of interest in me, asks for number and snap and kept trying to hang but i kept saying no out of respect to her man which is funny because even though she has 1 she would purposely play these games where I would be left on delivered and read while she posts etc. I stopped giving time to her and she came back snapping and texting me. a few days ago she asked to go to a party next week to which I said ill see but I knew I wouldn't. Out of kindness I sent a text asking if she wanted to hang and now I'm left on delivered for 3 days. Next time i see her should i act chill or give the cold shoulder. goal is to win mentally.
