Sad thing is, there is not much you CAN do when the daughter is 18. You can warn against, but the choice is hers. At that point, the parents are powerless. What are they going to do? "We're going to take away your college tuition." "Were going to take away your car" She's going to end up seeing him ANYWAY, and the more you push her away from him the more you push her towards him. Am I wrong men with daughters. Have any of you SUCCESSFULLY swayed your 18+ year old daughters away from a guy?
if you're rich you can cut their money supply off and write them out of the will.
