<human>: Me and my Gf have been dating for almost 6 months now.  Im 22 years old shes 23. This story is pretty confusing so ill try my best to explain it.

So about 2 months into our relationship, she tells me she was hanging with one of her guy friends and he kissed her, she was at least faithful to me and got upset and left and hardly talked to him much after that.  
Thing is the same guy, she had a one night stand with him about 3 months before we even started hanging out.  From what i got out of my GF is that she could of started a relationship with him but he fucked it up.  So a little while later they decided to just be friends. 
Now shes dating me, and this "friend" decides to change his mind and try making moves on my GF.  She knows its not the right thing to do and things become awkward for her and the "friend".  She eventually tries to end the friendship between her and the "friend".  
Things were going pretty good between us, at the time i understood it sucks to lose a friends and etc.  But later I learn, back when they hooked up and kinda hinting at the idea of starting something serious, his fuck ups "broke her heart".  

That sounds to me you were really into your friend, you had a one ngiht stand mistake and he fucked up everything else and that hurt you really bad.  

Only reason this is coming up again because the "friend" started talking to her again and finally apologizing for fucking up in the past, sorry for hurting your feelings so much etc.  

Thats all fine and dandy i suppose, until I find out how much this brings back memories and depresses her.  She STILL HAS small FEELINGS for this guy.  Wtf.  She has had small feelings for him since before we even started dating.  I dont know what to do about it, Take a break, Break up, Ignore it?  I feel like i cant ignore it, its too big of an issue and its getting in the way, I love her, but she cant have feelings for 2 different guys.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Long time friend and possible relationship of my GF says sorry and brings up bad memories and old feelings.  Unfair and makes me feel like shit.
