Marriage counseling could make a vast improvement. Both parties need to be onboard for it to work, though. Best of luck, man.
Depends?
My ex-wife wanted kids 2-3 years into the marriage and I never did.
I agreed to go to a licensed therapist with her on this issue.
The therapist concluded what we both knew and expressed:
1.She had really developed a deep need to have children and be a mom.
2.I never wanted kids and had zero desire to be a father.
She was horrified at first and (wrongly) assumed, I had something wrong that could be changed.
Good marriage counseling can point out what they issues are and how each person feels.
BUT, they can't really change how a person feels on key issues.
