How can someone stop having an affair outside their marriage?

I have no idea from the question who the “he” and “she” are – that is who is having the affair, who wants to stop it and who loves mom. Can you rephrase it to make it clearer?

meant to put “who loves whom.”

@janbb OP says He got caught several times I think it’s the man cheating. The rest is confusing. I think the woman wants it to stop but who knows.

How does the older woman feel? Does she want more or is it lust?
How about the wife, what does she want?

If they’re really in love and can’t live without each other, maybe a divorce would be the next step.
