Re: Problem with control issues
First of all, is this your son's child?
I'm assuming this girl lives at home and is maybe even being financially supported by her mother in some way. Since your son and this girl are going to have a child together, they need to get a place of their own, support themselves, and then that way maybe she won't be so attached to/dependant on her mother.
The grass is always greener on the other side...until you get closer and see that it's astroturf~
