How am I wrong for suggesting this?

Tears? Lies? Has he cheated on you? Accused you of cheating? Some more information would help but I’ll still answer your question.

Look, you are not wrong for wanting to move out. And really, I don’t blame you.. Your boyfriend started throwing things? Seriously, either something in his life is taking a fast downward spiral or he simply needs anger management. I would also think that he is quite possessive and needs to gain some maturity (even if something is awful in his life, he can’t take his anger out on you or anybody really).

And why is your self-esteem so low? He’s treating you in an unacceptable manner and you have to question if it’s wrong for you to move out? Have confidence in yourself and get out of there as soon as possible. Whether or not you break up is your choice but regardless, you two need some time apart. Perhaps in a few weeks have a heart to heart talk about your relationship and if it is the right thing at this time.
