WHEN HE IS ALWAYS COMPLAINING

Good day ladies. How are you doing? Congratulations to the new brides in the house.
As usual, I'll be sharing a fictional account of some true life stories for deliberation.

Ibukun and Sola have been married for a year. During courtship, Sola was really caring and compassionate. He was so in tune with Ibukun's needs and she could do no wrong in his eyes.
About 4 months after they got married, he started finding faults with many things Ibukun was doing. He has complained about her housekeeping skills, though they work for about the same number of hours daily. He complains about the meals, though friends and neighbours praise Ibukun's culinary skills. He thinks she is wasteful, though she rarely asks him for money.
Ibukun feels drained every day and feels so dejected and alone as she had to move to another city after marriage.
As usual, I have many questions.
1. Is Ibukun overly sensitive or are these serious issues that need to be addressed and resolved?
2. If so, what can Ibukun do to address the issues?
3. Are there signs one can look out for during courtship that could alert one to the possibility of such an issue?

Please share your views and experiences.
