I'm 15, and a man who was over 35 got me drunk (me being stupid accepted the alcohol) and then did a lot of things to me, half of which i can't remember except that it hurt, alot.

he works with my dad and is about to get married and i have no idea what to do! seeing as it was my fault maybe just let it go...

No! Even if you consented - you were still under the influence of alcohol meaning you couldn't think coherently plus you're a minor!
Have you taken a shower? Do you still have the clothes you wore at that time - have they been washed?
You may have accepted the alcohol but he gave it to you with the obvious intention of getting you drunk so he could do things to you!

If your clothes are still dirty from when that happened then go get a big plastic bag and put them in there.
They most likely have his DNA on them and since you're a minor he shouldn't have been touching you anyway.

But it wasn't your fault!

Definitely tell someone.

Seriously tell someone, and keep the evidence if they haven't been washed. You cannot be taken advantage of like that!

You need to contact someone as soon as possible it's still illegal.

Whatever you do, do NOT blame yourself.
It was not your fault.
Never say or think it was.
It was not.

You should tell someone.
I know how hard that can be.
But you have to tell someone.

Stay strong.

Tell someone. Creeps like that need to go to jail!

I agree, the guy deserves to go to jail, that's pretty harsh for him to do that to someone.

But i drunk the alcohol....No-one forced it down my throat. It's actually pretty bad cuz then he told me that he was getting married the day after!!! The poor bride.
