I made a thread a while back about how I have near 100% success rate with overweight girls and 5-6/10 but once a girl is good enough for me to feel comfortable walking around with, she is not attracted to me.

The advice I was given was that I probably treat the more attractive ones with more anxiety etc. Since then, I had gone on 4 dates from tinder. Lo and behold, 3 of the four girls are overweight (can't tell in pics) and it was an easy lay. The fourth girl is texting me a lot, more than the other three, keeps asking if I'm still up for meeting up etc. She shows up and she is a 7+/10, nice body cute face. Finally someone that i am truly sexually attracted to more than a one night thing to get my dick wet after a dry spell. I am feeling very confident since she had been showing more interest than The other three girls. Immediately, when I meet her, she looks at me and her body language screams "oh no". Hands crossed etc. We chat over a few drinks and we sit down on my couch and she crosses Her hands and crosses her legs the other way pointing away from me. I know I am pretty much fucked at this point. I don't give two shits and just go for the makeout - she is not too receptive and backs away. I just end the night a few minutes later telling her I have to get up early.

Why is this a common reoccurring theme in my dating life? Should I go monk mode and optimize myself physically (better haircut, lift more, tan, dress even better) before I go out into the scene again?
