Would this be considered a form of cheating?

We were together 4 years ago

He admitted to having several crushes that lasted months at a time during our relationship. He lied when he hung out with them - they were in the same faculty and on the council together in their faculty so they spent lots of time together but admitted to me (near the end of our relationship) that over the years he hung out with them (in groups or alone) at uni more than he admitted or told me.

He also said he masterbated to them all the time, and masterbated to them probs 70% of the time and 30% was me (he thought this was a compliment).

He also lied to me about texting them - said he didn’t but he did. He said it was only ever university related tho.

They would also talk between classes and stuff and stuff. During our relationship when I asked about these girls, he said he never ever talked to them unless he had to during meetings and never saw them between classes and stuff. Turns out he would see them every day and talked between classes and even helped them with homework - wouldn’t be a big deal if he didn’t have a huge crush and masterbated to them all the time.

This is basically all the info that I know. Who knows what happened that I didn’t know. But say that this was it. Would this be considered emotional cheating??
