What is the reason for the repeated anger between the spouses, the husband's abandonment of prayer, his feeling of a weight on his chest, and what is preventing him from returning to his prayers?

Abandoning prayer is one of the greatest destructive sins, and one must immediately hasten to observe it, seeking help in this by adhering to remembrance (dhikr) and supplication (du'a), keeping company with the righteous, and reflecting on Allah’s warning to those who abandon prayer.

One must treat his wife with kindness, in compliance with the verse: "And live with them in kindness." And if a problem arises without a cause, one should seek help through Ruqyah (definition) (Islamic exorcism) using the Quran and Sunnah (definition).
