AIO I broke up with my boyfriend after I caught him peeing in my kitchen sink

On Valentine’s Day, my boyfriend came over in jeans and a sweatshirt. I asked him where we were going to eat dinner and he said “I’m not sure. Where do you wanna go?” I was frustrated because although I wasn’t expecting to go to a fancy restaurant, most restaurants require a reservation on Valentine’s Day. We ended up having a two hour conversation in which I told him that I felt disrespected in the relationship. We ended the conversation with him being apologetic and saying that he understood and that he would change. We went to dinner. He had one beer at dinner. We went back to my place and he watched a movie while I put away some clothes. The movie ends and we’re getting ready to take a shower but I realize I need to use the bathroom. I told him I would be right out. I closed the door and played some music so he wouldn’t hear me going to the bathroom. I was in the bathroom all of 4 minutes and I open the door and his pants are down and he’s peeing in my sink. He quickly pulls his pants up and says “I wasn’t doing anything” and I said “yes you were. You just peed in my sink”. I have contamination OCD. He knows this and said “I was going to clean it up and you were never going to know”. I didn’t raise my voice or kick him out. I cleaned my sink (4 times). I still feel like there is pee in my sink. Two days later I broke up with him. Am I overreacting?
