I could not agree more with this. I get so pissed off when women come on here when they're in their mid 50s and older, saying they've had enough of their marriage, and their husband, (for one reason or another,) and a bunch of posters come on and say 'you can start over, you can retrain, you can find a lovely new home, a whole bunch of friends, and a fantastic new man!' (at 55-65 or thereabouts!.
It really pisses me off, because it's filling these women with false hope because the chances of starting a new career, and getting a really good new relationship, and an amazing wonderful shiny new life, full of wealth and prosperity at that point in their life is next to none.
Another thing is. As you say, after 30-35 years or more of being with a man, probably at least half of that time where you been pissed off with him, the last thing most women 50-55 plus want, is to start a relationship with another man again! Why would she? It won't be any different. So in many cases, it's worth staying. Not all, but many.
Also, any man interested in a woman of that age is very likely going to be 60-ish. So all she will be doing is swapping one grumpy, boring, balding, man in his 50s/60s, with a paunch, for another grumpy, boring, balding, man in his 50s/60s with a paunch, And HE won't leave. As has been evidenced by a post on here that I mentioned earlier, if a man has nowhere to go, he will never leave, as he needs someone to be his servant.
I have been married nearly 30 years, and to be honest with you, sometimes it's been great, sometimes it's been shit. Like most marriages. It's OK right now. There's been some days when I wished my husband would just fuck off to high hell. And other days he's like my best friend. Some days he moans like a little child about everything, and always has an ailment to gripe about... Other days he is a real giggle and a lot of fun, and we have a blast, and I couldn't imagine life without him.
To be honest with you, even though he gets on my nerves some days, it wouldn't be any different with any other man. I know some people on here claim to have perfect relationships and their husband does everything in the house and takes on all the childcare blah blah blah. But really most men are fucking useless some of the time. (Most of the time, some of them!)
If DH were to leave or die, I, (nearly in my mid 50s now,) would absolutely not have another relationship. I could NOT be arsed! I would prefer to stay with him though, because as has been said, it's often easier to stay than it is to leave, unless it's VERY bad. Many women, me included, have a certain lifestyle that is supported in part by the husband's wage. My hourly rate is higher than my DH, but I work less hours, so he earns a bit more IYSWIM. So I would struggle financially alone.
I'm not sure I would like single life to be honest with you. To be quite honest, unless you're quite solvent and quite wealthy with a 6 figure sum in the bank, it's a tough life as a single person, I don't care anyone what says, it's pretty shit being single if you're fairly poor, it really is. I know a number of single women 40+ whose marriages didn't work out, and they are alone, and their life is shit. They just work to live and can barely make ends meet. (As I say, these are the ones who are not very well off. If you are fortunate enough to be wealthy, then you're OK of course.)
I suppose being in a bad marriage is shit, but being single when you've got very little money is too. You have to weigh up the pros and cons. Personally, regarding my marriage; I will NEVER leave. I have a very comfortable life, I would not have if I left.
