<human>: My ex gf [20] and i [25] broke up earlier this year after dating for 2.5 years. she has maintained contact with me the entire time from april until now, finally admitting in july she was having an affair with a married man with kids.  i reluctantly took her back later in july after she realized all he wanted her for was sex, only to find out in october that she was still fucking around with him on and off.  it's finally gotten to the point where she actually wants me back, but she insists on talking to that guy still, and she's probably still fucking around with him on the internet.  i'm not looking for advice so much, but some fucking backup because she has me thinking there's nothing wrong with what she's doing and i **know** it's wrong.  help me reddit :'(

Can you provide a brief rundown of the text in within 3 sentences?
