I started talking to this girl a week ago, her (F) and her twin sister (N) were working out, I approached them said they were attractive and the one I was into (F) was asking me questions and smiling and we had a good convo, and I tried to keep her sister included in the convo as well, next week when I saw them I saw N was lifting pretty heavy weights and she looked at me and smiled because she couldn’t lift it anymore, N said I should try to lift it and F challenged me to it so I agreed, I lifted more than them and I talked to N a bit and teased F, before they left I asked F what her hobbies were, she said running and I said she mostly only does legs because she trains upper body once a week, I tried to say it as a joke but I don’t think it came across that way, next day N was still friendly to me but F wasn’t talking much, it was a short convo with N and I left because of the awkward silence, N talked to a group of guys and F talked to them too, I ended up seeing 2 girls one of which I knew and then talked to one of them for a while, saw another girl and had a friendly convo with her too, I saw N and F again and They were trying to measure their height and me and N were laughing because we didn’t know how the machine worked, F looked serious, they told one of the guys they talked to earlier something, he tried to ask if I was all good and they told him to shut up, 2 days later I only saw N, asked her about F she said she was fine and at work, she put a fake smile this time when she saw me and it felt awkward, I feel they either think I’m weird for always trying to talk to them and talking to women or F likes me and got jealous or thinks I’m a player, what do I do?
