No, I don't think you are shifting blame. I think the key thing you have realized is that the SITUATION has created emotion in you that you don't quite understand and you need to explore where this is coming from a little further. I think the thing to remember here is you could have put anyone into that scenario, or one similar, and your reaction would likely be the same. The fact that you are trying to figure out why he has that much effect on you makes the whole thing much more healthy. If you were just stuck in blame and anger and making the move to quit therapy, I would question your skills here but you are not. You see he made a mistake, it was extremely painful and it stirred up emotions that you can't quite explain but will work on exploring! I think it is great work!
