I don't know the whole story,there could be so much going on there that you're not saying that may deserves different answers.But let me say,I am a mom of 19 year old and a 17 year old and have a 35 year old and 40 year old step-child.Speaking from the experience I have with my own two biological kids,as a mom when your kids are at that age when legally they can do as they choose,it's hard for parents to let go and allow kids to take control,knowing they may be about to make serious mistakes,or premature decisions.and trust me a moms hind sight is way more than 20-20.I have made some doosey of mistakes that I am grateful every day my own kids have managed to avoid. And too when mom finally makes herself accept the fact that Sally is all grown up,sometimes she just has to bite her tongue,as much as she hate to feel the "defeat(so to say)"of letting go.And too when your kid is still at home under your financial rule,its hard for a parent to say,"Sure,I'll foot the bill while you screw it all up!"But hey,me...like so many millions of parents,and like you one day too....all have to do it.Be understanding with mom.Realize she's losing a part if herself,to someone else,she's also losing control,and knows that when her kid messes ip at that point,theres not much she can do anymore but sit back and cry about it,and honestly that's not an easy thing to deal with,like seeing your kid about to run head on into a brick wall and all you can do is watch even though your standing right there.Try seeing things from moms side.
