The weirdest couple

This girl I recently stopped being friends with has THE weirdest relationship. She dated this guy back in 8th grade. When he wanted to break up with her she threatened to kill herself. When he eventually did break up with her she spread false rumors that he raped her (she later admitted to it so yes there is proof she lied). She then dated this guys best friend *Tim. She basically used him and was cheating on him a couple times with different people. Now the original guy she said raped her, *fred, r currently back together now and I don’t see how he could get back with her. (Actually I can, he just wants sex). Reason I’m posting about this is cuz like I already said i think it’s weird and I don’t get how people can do that and forgive other for things like that.
