You should apologize to her for cursing her and tell her that you didn't mean what you said and that you are sorry about the hurtful things you said. You should also make sure you don't do it again.
Also make a personal note of the fact that she wanted to make you jealous to see how much you love her. I'm not sure how this is seen in your age group, but this is not a very nice behaviour on her part as well. You should ask yourself what will you do if she continues doing that?
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
