I met a guy in the club and then I went home with the wrong guy because I was too drunk to realize

I was very drunk when I met him on the club. I dont even remember his face but I do remember that he was very good looking. Anyways, I went home with him and when we were at his place I went to the bathroom to freshen up and brush my teeth with his toothbrush. When I came out he just looked at me very confused and asked me who I was. Then he called my Uber for me and send me home. Apparently he wasnt the guy. The funny thing is that he texted me the day after to check if I was okay and we had a little chatty. I was so embarrassed and I dont know how to explain because I cant even remember a single thing about the guy I was actually flirting with.
