Boyfriend says he thinks he loves me more than his ex wife if that’s even possible. Am I overthinking this?

He’s been divorced for 8 years. They’ve stayed friends. At one point after getting divorced they dated. This was before we met. She didn’t want anyone to know that they were divorced so they kept it a secret until about 2 years ago. We’ve been dating for over three years. He’s no longer spending time with her like he did when we first met.
