I need advice.

Linda
My boyfriend and I are getting married in September and he has a 4 year old son, he doesn't live with us. He lives with his mother. I guess he's been begging his baby's mother to let him live with us for a year okay I'm fine with that. But the thing is he doesn't let me tell his son no, or put any rules on him so then the kid does whatever he wants and crys when he doesn't get what he wants. So I told my boyfriend, I feel like we're going to argue a lot if he does end up moving with us because you don't like me putting rules on your son or anything. So he told me then I don't know if we should get married, I'm heartbroken.
