Sorry for the lack of response but I've been busy with everything these days..
Recently, we had another discussion about how things are affecting me in regards to her friendship with this guy and she stated she'd stop talking to him (not too sure how sincere it was though). Me, being the guy I am, refused this. Despite it having huge effects on both of us: I don't want her to lose someone she cares about. I also believe she'd just end up resenting me for this. I believe I can fight through this and told her as long as things are kept on proper terms (them only being friends) I would be able to get over the whole issue. I did put her in a position in which everything was dependant on her staying true to our relationship..this is because it's the truth.
Soon after she was back talking to him like it things were normal so I really am not sure how sincere her offer was although I'm glad she mentioned it since in the past it was "He is going nowhere" - this was said without me ever mentioning her to stop seeing him (I never have).
Tonight, she's off to hang out with him again because he just finished exams or whatever. I have to admit, I'm still shaken by this (and other * * * *ty things going on) so I will do my best to distract myself from thinking about it.
