reality though, people mature different, if you are compatible it can work.
Right, there is many things to consider before adding a wife.
I'm writing this as a general example for public reading (not for OP)
Mainly principles and maturity.
Even if both marry, doesn't mean they got to know eachother intimately enough to be happily married.
She might be worried about education and hanging out with friends turning up to loud music, she might not want a serious relationship but rather comfort in a cash cow.
He may not want to deal with her foolishness despite it's cutsieness but rather would like her to fulfill homely duties while he makes money to provide. He is charmed by her looks but now expects more out of her that she wasn't prepared for.
Which goes to show = regardless of age, people should be first and foremost mentally agreeable.
On equal terms passed initial attraction.
Because too many young woman marry a well to due man who is rich enough to comfort her needs but treats her like crap subjecting them to abuse.
In honest hands, you'd never know. Maybe rightful love falls in place.
But in my opinion OP is mad suspect just being a Xabeshithead Pervert.
