How do you know if you should break up with your boyfriend or stick

we've been having issues for a couple of months once I had a crazy work schedule and now we've been on a break for the last few weeks to give me time to "decide what I want" and it's been zero contact until tomorrow when we have to have "the talk"

Yet I don't know if I'm scared to break up out of fear that I'll regret it or because I actually do love him.

Feeling confused and conflicted and also avoiding confrontation because I don't want to break his heart.
