Just for your personal reference, i dated a guy just like your boyfriend. It escalated from his paranoia and verbal abuse to physical abuse where he'd slap me in the face IN PUBLIC (no one who saw him hit me, ever stopped to help me either which makes me angry in retrospect). Not saying that your boyfriend will physically abuse you.

But you are being abused right now by your boyfriend verbally, and he's manipulating you providing you with the shallow affection. It's up to you if you want to leave him.

But if your friends are noticing this too in your boyfriend, and people online are telling you that he's acting abusive, then you have a lot to think about. Is being abused by ONE MAN worth it? There are a ton of men out there you can date, who won't abuse you. The question is: what do you want?
