I met this girl a few days ago and got her number while playing pick up sports. Yesterday I called her to tell her I was playing today with some people but she didn't answer. I also asked a mutual friend of ours if she wanted to come out and play yesterday and she said maybe but she'd let me know. Today i texted the first girl I was into if she wanted to come out and play and she responded quickly saying yes, but to let me know if the mutual friend was going because they had plans but they got into a fight and she wasn't responding to her. This is where I got the gut feeling that she is trying to use me to figure out what the other girl is doing and doesn't really care what the other girl does. She just wants to see if she can control me. I fucked up and said I'd message the mutual friend but tried to save it and tell her to message her. She basically refused to message her again. I haven't messaged the mutual friend yet. I was thinking to just not message at all and if they show up tonight cool but if not whatever. Should I tell her that I am not going to message her because I don't want to get involved or just leave it where things are and see if they both show up since I already fucked up by saying I would message the mutual friend? Or am I overthinking?
