Yes it's hard!!!!
But you CAN do it!
YOU HAVE TO.
You know how practically all the time you hear about fucking shitbag men abusing children? And you think good god it's bloody everywhere, how can someone be like that?
THEY ARE MEN LIKE HIM.
THEY ARE MEN LIKE HIM!!!!
You are really young and you have known him since really young and you can't imagine anything else, but the tragic thing is that there is a bloody WORLD of lovely blokes out there, great people who will be a FRIEND to you and SUPPORT you instead of pawing at you like a pervert and making you act like a prostitute for kicks and to amuse his friends.
Do whatever you can to get out and I promise you that in a year you will look back and think omg I can't believe I stayed so long and I am sooooo much happier.
Be very clear - you are putting your daughter in danger by staying with him. You are RISKING her.
Don't do it. Get out get out get out. You CAN.

Most men don't have to be told not to show their friends videos of you doing sex stuff. Most don't have to be told not to grab your breasts in public.
I get that it's hard to leave when you've been with him so long, but if you can't do it now, at least start preparing. You wouldn't be posting here if it was all fine -your instincts are telling you that this man isn't right. Start saving money in an account that he doesn't know about. Do the freedom project or read Why does he do that?. If you can't bring yourself to get out now, at least prepare for a time when you might.
