My best friend was having sex with a nearly 50 years old and then tried to rape me and get me to have a 3 some with her and him, so I left and did not talk to her for a year... I came back in to contact we have been closer but also my boyfriend knows and hates her for it... I don't know... should I actually be staying in contact with her??

Oh dear... I wouldn't want to tell you what to do... But in my humble opinion, it's great that you stayed away for a year... Sometimes space is good. However, if you started back communicating just be really careful that's all... Keep your head on always... You both were friends & SOMETIMES people change & realize their mistakes, just be really careful.

What are you doing? Stay away forever, don't be so naïve.

I'd say you have a very poor choice of friends.
