There are many valid reasons why some parents have no option but to leave the family home. But for those who are simply unhappy with their marriage, leaving may not be necessary in order for them to find happiness. Indeed, leaving is not even a guarantee of finding happiness.
Being a parent has been the most fulfilling aspect of my life. I cannot imagine any other experience bringing me more happiness.
Having decided to stay in my bad marriage in order to provide my children with the best upbringing I could provide them with, I found that my happiness in life came from seeing them grow into two wonderful, well-adjusted adults.
Staying may not be the right solution for everyone, but it can be for many who feel 'stuck' in their unhappy marriage.
If you can love your child more than you love yourself you can find fulfilment that only comes from being a parent. That's not to say that only those parents who stay are good or loving parents. Or that those who leave are unloving or bad parents. I'm not saying that at all.
What I am saying is that in many cases, staying in the family home really can work for both parents and the children. And that true happiness can still be found, regardless of the marriage not being perfect or very fulfilling.
My children are both glad that I stayed.
So am I.
