Studies show the most common reason is because wives feel disappointed, out of love and unfulfilled emotionally.

Bordem, lack of interest and loss of trust.

An unfaithful partner who drinks too much. Well, that's my story anyhow.

All of the above.

people don't have trust, they don't have open communication, and sometimes, it's just patience. you see the couples that last forever, they have patience, they don't argue about money, well they might, but they wouldn't run on and on about it. be happy with what you have, and don't go off running after something that moves just because it shows interest. be faithful. i think those are most of the reasons nowadays.

Women are decietful lying bitches. #1 reason

Its lack of trust and in most cases it is ego.
