Just wan't to know. I'm getting married in May (I'm just 22)
Is it a good experience?
Every marriage is unique. Some go wrong, others don't, and age doesn't seem to matter much. It's more a matter of going together in the same direction and maintaining common projects. Strengthen each other.
My wife and I met when we were 18, we're now 36. We've spent half of our life together and we have 3 kids.
Thing is, what strongly links you to the other person changes over the years.
In the 90's our common points were that we were studying chemistry, reading lots of books, playing videogames over night and disliking parties, crowd and so on.
18 years later, she's a teacher and I work in computers : chemistry has totally left our lives. She still reads lots of books, not me. I still play videogames a lot, she doesn't. We still both dislike parties and crowd.
Of course our kids are taking the biggest part of our free time, but other than that we now share a same passion for thriller movies, languages, card games...
We're aware that the binds between us are in a perpetual motion, but we're also confident in our future as a couple. That's perhaps one of the keys to a successful marriage.
I don't know for sure, I can only speak from my one and only experience.
