I don't think you're being stubborn. It's natural to feel what you're feeling - and in the end, its your decision, of course.
However, let me share something with you quick (which I generally don't do, but what the heck)
When I was younger I was in a serious live-in relationship with someone I considered the love of my life. It was going in the direction of marriage and we had been together for 7 years. Eventually I found out he was cheating on me with a previous neighbor that we had. She was married. I was so angry that I ended up calling her. We ended up talking for a while and during the discussion I realized that while I had had time to ramp up and prepare for the confrontation, she was caught completely off guard. She didn't have time to think and it was clear that she was terrified. Terrified of what I might do to her physically, emotionally, and otherwise. While I had anticipated feeling powerful, what I actually felt was very different. I felt pity. In that moment she was begging and was utterly pitiful. What I also realized is that I was directing my anger at the "safe" target. While she had wronged me by proxy, I didn't know her. She was a virtual stranger. My real rage stemmed from a relationship much closer to home.
So after the call I had even more feelings to deal with - one of them being remorse for confronting the wrong person. I certainly fantasized about getting revenge, but in the moment it just felt...wrong. While I don't regret many things in my life, that is definitely one of them.
I know you'll make the decision that's right for you, whatever that is. I guess I just wouldn't have felt right if I didn't share.
Thanks and the best of luck to you,
