'I think your DD needs to find her feet, get comfortable as an independent working adult, live alone, pay her way, get a promotion or two, and especially she needs to leave one job and go to another be able to deliberately leave one thing behind and move on, in other words before she makes the move to marriage.'
Doesn't matter what you think. It matters what she thinks. And she thinks she wants to marry this guy. In a year.
Plenty of people don't 'find their feet', or live alone before marriage, or have what others consider an ideal adult trajectory in life, yet marry and are happy.
If I were 22 and I read stuff like this that my mother posted about me on the internet, I'd be extremely hurt to say the least.
I was an adult by then, a woman and not a child.
Plenty of people reading this have already had a child, or more, by this age.
It's hardly a teenager here.
