I would have just told her that do what you want, but I don't agree with it. I'm not going to lie, my daughter just turned 18, and I would be pissed as hell if she came and told me that she's dating a guy my age. If it was my boys I seem to think that it would be a little different. If one of my boys was only 20, I seem to think that my son would just use the woman. I do agree that there does seem to be a difference between just turning 20 then almost 30. When kids are 20 they are just starting out. Older 20's they seem to be around a little bit. Idk, I can't see one of my sons being with a woman that age, and the woman expecting that my son is going to pay her bills, and give her everything she needs emotionally.
