You say you love them but it doesn't sound like you're enjoying your bf's company.

What about your boyfriend do you love that doesn't even make you mention the thought of leaving him? Why do you stay with him?

I think you should consider leaving him. You've only been with your bf
for 5 months and he's already shown to be an abuser. There's a real possibility it could escalate and become worse for you, and talking to him about his wrong behaviour doesn't seem to be an option either. First of all, he's already crossed a huge boundary with physical abuse. He seems to have no consideration for your well being, at least in that regard. Then there's his temper, any conversation that includes you standing up for yourself and/or telling him your leaving could simply set him off. If you truly do leave, then i'd just depart without his knowledge.

Even if he does truly love you, love alone is not a reason to stay if he doesn't treat you well.
