You sound intelligent and self-aware, so it’s hard to understand why you haven’t yet recognized that ur in an abusive relationship. Anyone who monitors how you dress, who you’re with, and where you go is called a jailer, not a bf. And this has nothing to do with cheating, btw. This is about his desperate, pathetic immaturity and insecurity. Regulating your behavior like you’re a child may give him some sense of control in the short run, but in the long run his insecurity will drive him to even further lengths, until you won’t be allowed to leave the house at all. If this brand of abuse is what you envision for your future, then you’ll stay; otherwise, you literally have no choice but to leave quickly, before he begins exerting control in even more aggressive ways.
