I ghosted a cheater

Hey guys, I know this shouldnt matter but I'm in pain, and looking for something to put me at peace.

I ghosted my boyfriend because he cheated. It began when I saw his dating app profile updated. It was a Monday. We never discussed it because I felt it was petty and we had an agreement that we are in a relationship on the onset. I would check it every so often just for my own protection, but he has always been so attentive and taking care of my needs, and I looked into his actions which was pretty consistent. Plus, we really had a healthy relationship dynamic. We always talk about issues face to face.

The following day (Tuesday), I asked for us to meet. I confronted him about it but he denied. I knew he was going to lie, but I made him feel in that discussion that I knew what he did. We adjourned the meet up very peacefully.

The next few days was crucial. Day after that (Wednesday), I had dinner with his family because they were in town. It was the second time to meet them.

Friday night, someone messaged me asking about my boyfriend. To cut the long story short, she was telling me that they have been talking since last month, and asking if I am the girlfriend. I didnt divulged any information because I needed the information more than her. It happened like 1 in the morning.

I couldnt take it, so I blocked up him in every possible way he could reach me. I couldn't take the disrespect to give him a proper discussion. I did that because I know I wouldnt hear honesty if I confronted him about it too.

Would like to know what do you think would be his reaction the moment he saw that I blocked him everywhere.
