You're going to get skewed responses on here @SleepingNWeeping The 'I married at 19 and am still married 40 years later' brigade will be roaring about how unreasonable you are, but I reckon you meant NOW. Is it too young NOW?
And I think it is. It suits some, but not all.
If my DD had said she was getting wed at 22, I would have been surprised, and a little disappointed TBH. I feel there is SO much more she can do with her life than getting hitched at 22. She is well-educated, intelligent, and ambitious, and has so much more to give - and so much more to do - before tying herself down with marriage and babies...
She is now 27, she as a university degree, she is climbing a successful career ladder, on a high salary, living with her boyfriend, and has travelled to 15 different countries in the past 9/10 years since she started uni (as well as 9 different countries with us as a child.)
I just can't imagine her being married at 22. But as I said, it suits some.... Some young women want nothing but marriage and babies, and that's fair enough. I know several girls/young women who got married at 20-22, and it's five to eight years on, and they have 2 kids each and seem happy as pigs in muck. So there is no one-size-fits all.
When I was a teen (1980s) LOADS of girls got married between 18 and 22, but around half of them were divorced within 5-10 years after realising they have nothing in common with the man they married, and by 27-28 years old, they were quite mature and grown up, and their 27 y.o. husband had spent much of their marriage behaving like he was still a single man, and was still very immature mentally...
Some of those women are still married to the same man though, their kids left home 10-15 years ago, and they are very happy.
I think 28-32 is a good age to get married, but as I said, there is no one-size-fits-all. Everyone is different.
