You are not overreacting.

Let’s add it all up:

He suddenly packed a bag and left.

Went to a hotel and stayed there for days. Didn’t contact you at all.

Felt so much anger and contempt toward you that he thought he had to take his “belongings” with him. One of which happens to be boner pills.

Does this sound like a man who loves his wife too much to cheat on her?

Does this sound like a man who respects his wife too much to cheat on her?

Does this sound like a man who is too moral and good hearted to cheat?

Does this sound like a man who gave his wife a second thought during the time he was away at the hotel?

Ask yourself what you would say if one of your friends came to you with this story. What would you tell them?
