Can you give me your honest thoughts if you think my ex bf was cheating on me or not?

I broke up with my bf of 3 years about 1.5 months ago. Through out or relationship, we really had two recurring problems. 1. he barley texted me, ignored me for most of the day, but would be texting and calling all of his other friends (who were girls), and 2. he would be way too close and overly friendly with girls.

I was never really against him being friends with girls, but anytime he was, he would ignore me. He would just ghost me for hours. An example of this would be he would send me a morning text, we would see each other at lunch 11 am), and then not hear from him at 5/6 pm or even later. Or hewouldn'tt text until late into the afternoon, even though he would text everyone else, including all the girls before me. He would also on weekend hand out with them on Fridays and not text me Friday night and text me at 36 pm Saturday.

He was friends with this one girl, and this girl actually sucked. I come from a very unstable home, and she was my ex bsf for years and knew about my struggles and would tell everyone my business in hs and gossip about me. I told my bf this, and he still chose to be friends with her and go to her house and hang out with them all while not telling me and ghosting me even though they talked about me. He even told me once that this girl and her friends was confsued on why he would hang out with them so much and not me.

After that phase ended, he would text me regularly, then he started hanging out with this other girl, and he friended a group. I didn't know them very well, but I knew they were kind, but the same issue happend were he would ghost me up to 8 hours, hang out with them more than me, not prioritize me and just hide things from me.

Again, in this, i this happenein d class. He was in her class, and they had a group project. He and three girls. He stayed at her house the whole night and wouldn't tell me he was there and didnt even text me. He ended up oversharing about our sex life and showed me my period app. He would also lie and hide things from me constantly about them. He would make plans to go drink and get high with just them alone.

I had zero trust in him. He then told me that after we broke up, he watched porn even though I told him it made me uncomfortable, and HE told me that he thought watching porn was weird and disrespectful.

My friends think he's lying to me and that he did cheat, even though he denied it. They said that maybe he was hiding because I was already so mad at him. And that the stories he told me, he was probably hiding more than what he told me. We broke up because of this, of him not respecting my boundaries and not changing and making an effort.

I know you guys don't know me or him or our relationship, but do you think he was cheating? I truly have no idea, and this has definitely been a hard part of my healing.
