One of my best friends was married for over 30 years, 3 kids grown up and left home. They separated and she met a guy on a dating site, first time since she was a teen. They hit it off and are still together over a year later. Her new guy never married but she is still legally married which complicates things. But they're Jewish, and she can't face taking him through a Beit Din. They split the house and did everything amicably. BTW this is in the UK not the US. I believe God gives us all a break
