I seriously need some advice

[BabyFacedAbortion]

She even said once if my friend ever left her I'd be next in line.

She won't because she's still very much in love with him.

Those two lines stood out to me. Would you be satisfied with being second best, seeing that your best friend said it was cool? How would he react? Bros before hoes hon, even if the love is true.. I think if you really care about her, you'll figure out a way to get your best friend to end the relationship with her..so she stops being hurt and then play it by ear from there. I wouldn't break up the two with the intention of dating her though. I'll hopefully think of something more helpful tomorrow morning..as it's almost 3 a.m and I'm kinda buzzed. <3
