Greetings Nairalanders.
I bless you my reader in the Name of God Thy Father,Son And Holy Spirit,Amen.
I sincerely seek your contribution in the said topic above.
Please Nairalanders, How can one achieve a fulfilling marriage?
At what level or stage in the marriage can one say it is fulfilled?

Excrepts: I have been battling with it. it is true that marriage one didnt prepare for will confuse one when it gets there. am in a s tation of confusion. I could say i never took time to prepare for it. how is transformable preparing in marriage? can someone activate a partner to begins to share the same vision ? ways of activation?can you force a partner to share the same Faith? having a different mission,can such marriage work? way out. A marriage where the wife is not submissive, go different Church, baptize the only child her, open her ears without the consent of the father? Is it advicable to go ahead with the white wedding ? can white wedding bring a change in marriage?
