When you face your karma, what will you do?

I was talking about my weird experiece two weeks ago with my friend. Basically, I just happened to saw my past life in front of me (it never happened before like this), and I found out someone around me had really bad karma with me. What should I do? My friend said, "you should go confront him and kick his ass." I paused. Then, I said calmly, "at the end of seeing my past life, I made a decision. No matter what happend in the past life, I will love and support him forever from now." My friend was in shock. Yes, my dear. You want to get tangled in the same karma all over again? Go punch your past life enermy and kicked his ass. Just don't do anything too stupid to get you to jail. Yes, if you don't change, you will fall into the same patterns again because you still don't learn the lession in this life. It will continue (according to Buddish and many other systems.) Life is full of choices. For my case, it's a little bit complicated. See...ok, for this guy, we were actually a coupld in the past life. We had loved each other deeply. However, we were too alike. We were too stubborn to express our own feeling with love when we faced obstacles in our marriage. We finally had lots of misunderstanding and he had an affair with my best friend. Did I hate him at that time? Hell Yeah! My roommate saw me talking about my past life with non-stop tears and she was so scared. She, also a sensitive person, felt such rage and hatred, sadness, sorrow, regrets, and all strong and negative emotions coming from me ( I felt it was from my 2nd chakra. My roommated said one of my screams was so horrifying like someone just died right at that moment...). At the end, I realized how much love we had had in the past. Why would I want to bring those unnecessaries to this life of mine? It took determination to let go. However, once I said I would love him forever, the extreme tense was gone in a second. That person may never know what happend between us in the past. It's me to decide if I want to carry those negatives to our future relationships. Why not let those go? It's you who is withholding it. The other person may not even know. Holding it is just to torture yourself. Only love is the answer. Hatred is never the way out. The first thing you need to do is to forgive yourself. You cannot change the past. However, you can change to future. Do you want to suffer from the bad karma once again with this person? If you already know what will happen without getting out of it, why would you choose the difficult way to live your life? I didn't. It's not easy. If this happend 6 months ago, I would just confront that person and keep giving him difficult time. Thanks to all the meditations, chakra cleaning, crystal energy, and Avartar tools I had access to, I have the strength to support myself and decide to let go. I just wish all people can decide to get out of it if they are facing their karma...Revenge is not the answer...Loving yourself is...
