I get the impression his husband may not have treated him very well during the marriage. There was something I read recently ish, earlier this year, I can't remember where or even exactly what, that made me think that was the case.His husband Dan is awful though. I could never understand what Rylan saw in him because he was a right knob when he on Big Brother. I think he latched onto Rylan because he wanted to be famous. He even tried hosting This Morning with him (he was tit at it).
The episode of cheating seems to have been very early on in their relationship, before they were married. It's still not going to have lessened the hurt or mistrust though.
I think he's been quite open and honest about why the marriage ended and his wrong doings. He hasn't bad mouthed Dan. I think the moans about paying for a divorce are just his way of making light of a situation that is incredibly stressful which is understandable given how mentally unwell he has been.
