5 years ago a girl used me for 2 months as fun hiding the fact she had another guy who was on ship at the time and she been fucking with him 7 months before she started with me. When he came back from the ship she started completely ignoring me. Then she briefly called me, admitted me she had other dude and how he's back and that I'm of no use to her anymore cause she decided he is going to be her boyfriend, then blocked me everywhere and moved out with him to other town.
It was the best motivation to get better.
