What makes a woman get a group of guys to jump the other guy she use to like because he rejected her because she came back after rejecting me first?

PS she ghost me flake on me in the past now she comes back trying to talk to me but i lost interest am i the problem if she pick someone else and i was just an option i dont believe a woman can still love a guy she cheated on, i just think she did it on purpose i use to thought she was my soulmate but i wish i never wasted my time on her because them guys flake on her now she treating me like im her last option
