*For all the 20 ones you know, there are posters and myself who know just as many that just aren't happy or any it it because they can't leave for one reason or another. Some people also realise that they aren't prepared to go through the rigmarole of finding someone again.
Society revers partnerships/coupling up, not just socially but legally too (I know, I used to be married - tax breaks being one o them!); most people whether unknowingly or not, have been conditioned to aspire to this status and to hold on to it as long as possiblefor the fear of being alone/lonely/isolated/financially worse off....you never know what goes on behind closed doors as being single for note than a few months in your 30s onwards, is seen as a pitiful status, so they get out there quick to remedy this problem.*
The 20 happy marriages I mentioned about ARE truly happy. You can read in their eyes, humour, face expressions, genuine feeling you can't fake if you are unhappy.
I know it because they are my close friends. They are girls/ladies of my generation late 30s+. Some are from my school. some from college, university, my school years training club & gym, my work colleagues, relatives who like talking to me and I like talking to them and discuss different life and relations situations honestly. We talk openly about their and my relations too. Some are married 2nd or 3rd time but happily this time. I also know about 10 happy not married partners living together couples. 5 of them are planning to get married within 2 years.
It looks like because you divorced and had a negative experience at the end with your own marriage, you don't believe so many couples can be and can stay and are happily married.
My parents also divorced when I was 5. My grandparents stayed happily married for 47 years till my grandad died. They showed me a good example of love, respect, and devotion for each other.
None of my close enough friends stayed married not loving their husband for the sake of taxes or because they couldn't move out.
Those who truly want to move out always will. Where there is a will, there is always a way. If they didn't then they had secondary benefits they decided to put up with at their own unhappy expense but none of my friends did it. Those who were unhappy left and met other spouses to be happy with as I mentioned earlier.
