It’s clear that when her husband left her 23 years ago, she was blindsided. She even said on Celebs GD that she has never recovered her joie de vivre since then. Earlier in the series they asked her if she had loved Ben. She said she was happy to love him because he seemed happy to be there. That sounds to me that she just wanted to be in a relationship, that wasn’t love. The way she is with people she considers beneath her (most people it seems) I can’t imagine she saw him as an equal. Ben is a tool, you only have to look at his cheesy Instagram, but based on her performance on Celebs GD I bet he had to tow the line and bite his lip a lot. Not sure whether he loved her or the lifestyle, but it would not have been an easy life being a second class citizen to her first class persona.
I would love to hear her ex husband’s story. I think he had an affair which caused the marriage break up. But a life time shackled to her would not be easy. Rather than grab at every job that is offered her (which just looks tacky and greedy) a period of self reflection is needed more before she embarks on a new relationship.
