A lot depends on her definitions.
If, by financially secure, she means he has a stable job and will not expect her to support him, then she may find somebody.
Really, I think the best she should expect is a guy over fifty with a job, able to pay his half of the bills, and not so obese as to have health issues.
I think the word “adventurous” is a giveaway that her expectations are unrealistic. She is describing a movie star, not a realistic potential mate. And looking for someone new to have children with at 42 is red flag that she’s well above the crazy line.
‘But how do you meet a man who shares your interests and accepts that you are an independent, strong woman when you’re in your 40s?’ she said.
Men don’t want their women to be independent of them. They want a woman who is on the same team, a partner in a whole greater than its parts.
As far as “strong”... that can mean a lot of things, many of them on the south side of unpleasant. Strength comes in many forms and it kind of sounds, with that self-description, like her form is radical feminist AKA hostile to men - so again, another reason for no man to want to get near her.
Two “failed” marriages and no tale of how the man was a horrible person = she was the cause. More red flags.
A woman still in her 40s relying on sex appeal alone is in BIG BIG trouble. She certainly isn’t going to get the dashing handsome hero from her favorite movie, as appears to be the demand.
