AM I A HOE?

The other day it was about 100 degrees and I decided to go to the pool with some friends. At the time I was taken (I’m not anymore because I felt guilty). While at this pool I hung out with my ex bf/crush. We were playing around a lot and he was holding me by my theighs, picking me up from my butt. Doing fun stuff we used to do as a couple. Then after swimming and walking home with him for about two hours I told my friends that I may have had feelings come back. is this considered cheating? should I tell my ex-boyfriend? FYI we’re just taking a break.
