Love... Never do this...

If you have kids with someone don't marry them for the kids marry them because you love them. Never just marry a person just to be marrying there is a special someone for you.
If you don't trust them don't marry them just yet wait till you know them for sure
If they abuse you and don't love you then LEAVE DON'T STAY. Leave because they don't deserve your love they don't even deserve you they just break you and break you and abuse you and you don't deserve that no matter how many times you feel you do you don't you are more than that. You are a human being not an object where they can just  beat on when ever they want or when something is wrong. Go live your life and don't be afraid of them don't be afraid just go. You deserve more than they show or give.

Talk it out and try to work it out but if it doesn't work then its best to leave but sometimes talking does help out more than you believe.
