Weng, who is still sharing the marital home with Ron in Somerton, Somerset, said yesterday: "We knew it was coming, for a long, long time. What pushed me to make a decision on having a divorce from him was when I was told by Ron that he had let that Filipino sleep in his bed.
"That made me really, really angry.
"What's the point of me trying to understand him and his ways and care for him, to be cheated on?
"How can I believe him? The intention was there.
"I even messaged the girl to let her know Ron was married. The reply I got from her was 'I'm sorry but I love him'.
"She doesn't know what she's getting into.
"They have been talking - just two days ago. They have been Skype-ing while I'm here as well."
Asked if she could end up being wife number nine, she added: "It looks like she could be."
Ron who has written a book ''lord of the wedding rings'' admitted that nine months ago he started messaging other women via a dating website but claimed he "didn't know what he was doing" due to medication he takes for Parkinson's.
He said he messaged "one or two people" sending them around £300 and Weng was upset when she saw the messages.
Around a month ago he went to the Philippines a and ordered a leg massage in his hotel room, which was carried out by Iza.
Ron said there was a security lock-down due to President Obama attending a nearby meeting which forced her to stay in his hotel room.
Ron said yesterday: "Basically I have been pleading with Weng not to have a divorce, but she has lost trust.
When it was time for her [Iza] to go and she couldn't because of the convention I said to her 'you better stay here if you want to, but it's up to you'.
"She slept in the bed, under the sheet, wearing all her clothes and there was a pillow between us.
"Nothing between us happened.
"I came home and told Weng that I gave this girl a bed for the night because she couldn't get back, and for her that sort of done it.
"I was being honest. Perhaps I shouldn't have said anything."
