boyfriend issues

my boyfriend and I have been together for about 8 months, we’re in the same grade, and we fight quite often about little stuff ( for ex. my friend sent me a video of a famous like tik tok guy and i replied hot and he looked through my messages while i was asleep then we fought and he leave me on read for 2 days ). it’s hard not to fight with him because he starts little stuff like that and i’ve talked to him and told him i don’t want a relationship like that. Idk what to do because i feel like it’d hurt him or regret after if i broke up with him.
