Lack of attention from the wife.

I have said many times that I do not condone male infidelity. But, whatever the circumstances, two are always to blame for family discord. Your partner, just like you, wants to feel loved. But when he does not receive affection, attention, trips to the "left" happen. Alas, not all couples are able to resolve conflicts peacefully. Each of the spouses stands up for their own truth. For example, a woman does not want to make concessions, because she is already busy arranging her life and raising children. While the spouse does not seek to support his beloved, but only reproaches her for indifference. The end result is betrayal.
