Relationship

me and my boyfriend had been going out for all of high school we had our ups and downs but senior year was really a great year but it all started to change the day we graduated that same day we graduated he accuse me of cheating with a guy who sat next to me during the ceremony. we continued going out throughout the summer I got a job and he started ignoring me for a whole week then he came back he said he missed me we got back together whatever you wanna call that then he ignored me for two weeks during that two course week the last convo we had he said we’re done I was stressed about school about money about everything I honestly didn’t even pay attention to the fact that he said were done. I didn’t have anyone to talk to so a coworker and I started getting closer I developed a little crush we didn’t do anything we were just talk about life and my coworker just happened to get out of this long-term relationship too so we kind of understood each other so two weeks past my ex text me I miss you so we got back together a week into us getting back together he found out that I had developed this crush and he flipped. he accused me of cheating.

We’re no longer together but i keep thinking.

My question is was it really cheating he said we’re done and all I did was develop a little crush I didn’t do anything physically with my coworker.
