Would you forgive a friend that have backstabbed you?

For me, I hope this wouldn't happen to me at all throughout my whole life, but if it does happen, this is what I'll do. Based on my current personality and principles in life, I would forgive that friend only if he or she truly repented from that incident and have intiatiated a public apology to me. If not, I might or might not forgive that friend. Since I am a Christian, and in Christian teaching Jesus says that we should forgive everyone, regardless of whether they repent or not; in fact, Jesus even asked us to love and forgive our enemies! I find this a real hard thing to put into practice, but I'm really trying hard to be able to forgive everyone I have something against. Indeed, emotions of anger and frustration can really overwhelm us sometimes....it really takes a lot of will power to avoid emotions taking over, and let your "kind" side of your being take precedence.
