Longgone you say your 19 year old daughter is recently married and in finacial trouble which we all know is not a good start to a marriage but hey thats youth isnt it .
I gather you are in the states ? do they have Govt assistance programs that help young people that they can take advantage of ? Charities ? religious organizations that help people in need ? Dont let her be so proud that she cant accept help from any source that will give it
Lots of young couples make bad choices in their early years of marriage and then become productive citizens in later life. I speak from experience here.
Accepting help from whatever source can mean you live a happy life in the future.
I know you want the best for your children but the bottom line is sooner or later they have to stand or fall on their own two feet. and you dont have to feel guilty about the choices they make .
Take care.
