Maybe it depends too on how you see yourself when in a functioning couple, just an adjunct or an essential part?
I know there are people stuck in horrible situations - living abroad married with DCs and unable to leave their DCs when the relationship fails; trapped by poverty; carers for family members - who can't break free.
I don't condemn anyone who wants to give a cheating spouse or partner another chance. I think it takes guts to go and guts to stay.
DCs do complicate matters. I worry that women do put themselves through the mill to try and keep things going at all costs for their offspring. And by the time those DCs grow up and leave the nest, what impression of adult relationships and attitudes do they have?
My parents' generation (okay generalising here) might have clung onto the notion that living without a man, or 'significant' other meant a woman was disadvantaged, downtrodden or undesirable.
I feel bad for people my age who say well, I am not likely to find anyone else/do better at my time of life. As though happiness were the preserve of the up to 49s. For me personally, the empty nest was a big milestone. Had my DH and I felt we'd seen the DCs grow and reach adulthood and our job was done, if we hadn't felt anything was left for us as a couple we would have reassessed and maybe made major changes last summer.
Last summer it was reported that the divorce rate was rising for the over-60s, okay there are more over 60s nowadays but there's been a loss of stigma over being divorced, and more financial independence for women.
Relate said at the time that over 80% of people surveyed aged over 50 said that strong personal relationships were the most important factor to a happy later life.
For anyone on the cusp of a new single life, good luck
be happy.
