Advice is cheap, divorces are expensive.
I would want to know that the woman has no health, mental or
physical issues. That means a complete physical for her and perhaps
a bit of counseling. If her attitudes about sex and sharing your life
are not engendered by any of the above problems maybe you
need to make her an offer she can't refuse. levity
Some folks are just incompatible. Some grow up and progress,
some do not,If that is the case make yourself a new life.
But don't forget your obligations to children.

Beware, amatuer marriage counselers are very dangerous,
because most of them have their own issues.
But hell redhook needs some competition.
Good luck.
