I need help

You don't. He was there first. Gotta respect the rule. Tell your parents and let it be. I was in a similar position, I did not act and got a lot of pain for it. I do not regret it.

Is she in love with you? You should check with your bff .. where you can love her and she can love him ..and later replace "love" with "marry" ..

Plz help

Ignore how you feel. Shes taken. Deal with it. Find another girl. Your young enough to just do that.
