Is it unforgivable if your bf spits on in a public place you because he thinks you cheated on him?

Aside from this obviously abusive act, I am sure that a person who would react like that about anything is not suitable for any relationship. Do you really want a hot tempered pathologically jealous man in your life? Please don't say he really isn't like that; people are their behavior. If you continue, expect more of the same--or worse.
