Serious situation dealing with sex

ok, its me Hayden again, right at the time I was 16 and my girlfriend was 2 days underage at the time of the finding out, we had sex and it was like the best! anyway my mom already knew before that, but my step dad just found out, and he went...

crazy,
anyway it ended with my mum and andrew knowing (sted dad). we came to the conclusion after hours of arguing and screaming at each other that he wont tell the father of hers and I can keep seeng her aslong as I dont get her pregant.
NOW heres the bad thing, my stepdad is a P***K, okay it has to be said because on the day of the arguement he pretty much told me I should hurry up and die, so dont take any symphony for this guy, he just wants my mum. that I can live with, BUT I know some where down the line in a few days, weeks, months whatever- hes gonna say something on perpose to my girlfriends father. and just the other day when my girlfriend turned 16 her father said to her just because your 16, doesn't mean you can have sex now (if she does se has to move back up north and live with her mom) ... HOLY S**T!

What should I do?!

should I go round and tell the father myself... or...
have faith in my step dad and pray to god hes not going to tell...

what would be the right thing to do?

I dont want to lose my girlfriend but I know something seriously f***ed up is going to happen, and/or my stepdad is going to punish me someway for something, using that!

Yet again HELP!

ummm, the right thing is tell her dad, but I see how much you love her, so you should tlk too your stepdad, I know what having an a**hole stepdad is like, but sucking up works... lol... hang in there, im sure youll figure it out

Sounds like the first one to talk to is your girlfriend. After all, she's the one that might have to move up north because of it all. Someone that you don't trust knows your secret and the only way to avoid having this blow up in your face is by letting the cat out of the bag. What I'm trying to say is that you can't count on your step dad keeping quiet and it would really suck that her dad found out through someone else. I think he would be much angrier and feel more of a fool therefore be less willing to forgive if it came from an outsider.
I think the best thing is for her to tell him before he finds out. I'm not saying it will be easy but hey, who said growing up was easy? The right thing to do is talk about it with her and see how she feels. She's the one that will have to deal with the consequences.

lol don't tell her dad people have gotten shot over that. You need to buddy up too him and become friends and make sure he knows your right for his daughter, so when or if he does find out he wont get the 12 gauge.

Really, if you think about telling him remember this question Have you ever been hit by a grown man?
