I like the idea.? It is certainly topical with broad market potential.

Some thoughts:

1]”asks for a divorce”:? shorten to “divorces him”.? Unless that’s your intention: she only threatens, doesn’t follow through.? Otherwise asking is different from following through with the divorce .

2] I suggest switching the protagonist to a female.? Why?? Because of the demographics: on average, women outlive men by more than a decade. Consequently, the pool of women in the senior citizen dating market greatly exceeds the pool of men. Women have to compete harder to find another Mr. Right.?

So it ups the ante in terms of the struggle, the ordeal if the protagonist is female.

3] And she’s not just eccentric.? I suggest that a defining characteristic that would be more in tandem to her objective goal is that she’s shy, insecure.? She’s not comfortable with having to be a proactive suitor. That’s what her 1st husband did.?

Now she has to get out there and hustle.

4] “embraces single life”:? On the contrary, it’s the last thing she wants to do.? It’s an ordeal, something she does out of desperation, not out of joy, not out of a sense of liberation.

5] I surmise that the Boomer generation is not likely to use apps like Tinder. Why? Because they are not interested in one night stands, zipless f**cks,? short term hit-and-run relationships.? At that stage in their lives they don’t have the energy, the psychological stamina, or the inclination.?

What they? want is commitment, a life partner, a stable till-death-do-them -part relationship.

6] Oh, and a guy who can produce documents to prove he’s financially secure, has a good insurance program — women don’t want to get stuck with? a financial leech.? (That is a real life risk.)

Best wishes with this idea.
