My mother remarried later in life. She met my stepfather at a widow and widowers club and they were together for about 30 years before she died. He recently married again at the age of 92. He was younger than my mother, but his new wife is younger than him, at 70. She's younger than me! They met through church, I believe.

That's the key I think - meeting in person, through social clubs and activities or hobbies.

My mom's dating at 62 and she seems happy, so. 😊 I just make sure she takes no bullshit, because women from that generation are often raised to take shit (read: abuse).

Of course it can, multiple times, at any age.

So can romance scams, so it doesn't automatically mean every proposal is good!

If she knows the person in person, they've know each other for a long time (imho two years is when people start knowing if it's love or infatuation/lust), and they love her and she loves them back and she wants to marry them (and imo if they've tried to lived together for a while to know their lifestyls are compatible), and it's not just based on fear of being alone; it's all good. As it is at every age.

But she's also an adult and knows her heart better than you or I, so she can decide for herself what's good.

Of course it can. And 58 isn’t ancient, she still has a long time left on this earth and deserves to find someone to share it with.
