this is something i need to discuss

i’ve had a couple girls flirt and try and attract me, nothing serious but i had one girlfriend that cheated on me fucked all my friends and this obviously did what it should have and sent me into a cannon event, met myself in the gym standing at 6,1 lean and i’m trying to get a better physique as we speak, but everytime i talk to a girl they either just randomly start ignoring me or start changing the way they speak to me and judge me off the way i look?
