That friend could have killed him. People literally stop breathing on Xanax and alcohol and suffocate. Your friend nearly murdered him and you still feel bad for her? She's a stone cold killer in the making.

If I were Jake I wouldn't want anything to do with you. That you were still 'hurting' and 'not wanting to add insult to injury' to someone that raped me would mean you weren't even worthy of the friend zone, that you were dangerous to know and be around. I would never want to be alone with you and I would never feel safe around you.

If you were into him you would be ravenously ripping this 'ex friend' of yours to shreds, the one that drugged him with a lethal combination of chemicals and then raped him. You aren't. If I were Jake's friend and you told me this, I'd tell you to stay away from him.

'Adding insult to injury' would pursuing this man that deserves someone that doesn't have the first thought about supporting the rapist that victimized him.

Your perspective on this is completely messed up. You need to let Jake be a friend. I think that you will hurt him if you pursue anything beyond a platonic friendship.
