If the girl wants to hold two jobs to help her husband learn that is her own choice. I know plenty of rich people in the U.S. who work like dogs just to drive a nice car.
As far as you Chani, you can’t get stressed about your daughter, it dosen’t help anyway. There are ways to help her though, There is a website called http://WWW.ShabbosKodesh.com in which you can send a whole Shabbos to your kids in Israel. I do it all the time and it’s a real break for my kids.
