He called me a bitch!

today I was trying to tell my boyfriend that we should take a break for a little bit since things have been rough lately since he is in the navy and we don't talk much as we used to. And I was being calm about the whole situation and then he gets mad and calls me a stuck up bitch.

hes never said that before he's always sweet and gentle with me and it just really hurt me and I forgave him for it and we decided not to take a break so were still together

I'm not sure how to move past what he said yes I forgave him for it but it still hurts a lot. help
