What do you do when?

telling the truth, everybody snaps sometimes.do you do this often? maybe you have an angry problem. be honest .there must be something that bothers you,

i'm going to assume the person you like/love is a girl.

besides the obvious of apologizing, let her know that you realise that what you did was wrong & that you don't want to do it again (& mean it)

ask for her help, and don't try to push things to re-establish the relationship, especially if your frightened her.

good luck

First off apologize and explain yourself, then make it up to her in a special way not something cheesy something meaningful and from the heart, if it's not sincere there's no point in doing it at all.

Doing everything your partner loves (be it buying her favorite food, candy, stuffed animal, movie, etc), going to your knees asking for forgiveness, and expressing truly and meaningfully how the partner really means to you.

That's what I'd do. Oh, and never get irrationally angry at them again.
