I personally don't know any couples who are genuinely happy.
One couple I know have both had numerous affairs, got caught and separated and got back together yet on Facebook are a big happy family. I think it happens a fair bit.
Other couples I know are unhappy but won't leave because either:
A) not bad enough
B) financially not viable
C) desire to keep the family 'together' too strong
D) think this is as good as it gets
On these boards you read about couples where one partner is abusive. There is physical and sexual abuse but also emotional and financial abuse which is even more common. Many people in these type of relationships don't even realise they are in an abusive relationship.
Then there are the couples who are happy but are unknowingly living a lie. Undiscovered mistresses, prostutute visits, flings with exes. Hidden sexuality or other secrets such as secret children, gambling addiction, drug addiction or other deception.
I am single and my main relationships have ended due to infidelity or ea.
We are told that a third of marriages end in divorce but how many of the remainder are happy marriages?
