Am I crazy?

My boyfriend said that I'm acting crazy bc:

We were at Subway and he went to the bathroom. (#2). There wasn't any toilet paper or paper towels. There was however a shirt in the trash can that had already been used by someone else to wipe shit off of their ass. I'm mad that he did that bc 1. He could've asked me to get him toilet paper 2. He could have some disease now like aids or some shit and 3. its just fucking gross. But I'm "acting crazy" bc I got upset about it. I'm like extremely grossed out and don't want him to touch me or anything now. Maybe that not touching part is crazy but me being grossed out isnt. At least I don't think so. What do y'all think?
