Ms Churchill has also received a text message from her ex-husband asking her how he could repay the money - and saying he forgave her.
She said she sent him her bank details but had not received any money.
Dahab locals wanted people to know "not all the Egyptian man like this" and their community was a safe place, Mr Soliman said.
The tourist hotspot is known for its diving, windsurfing, camel treks and proximity to biblical Mt Sinai.
Ms Churchill said she had been contacted by two of her ex-husband's former girlfriends - one in Latvia and another in Egypt - since the article was published, who told her it brought back bad memories.
Ms Churchill fell in love when the pair met while she was on holiday 10 months ago. After a return trip to Egypt, she decided to settle with him in the South Sinai.
But the relationship went quickly downhill and she ultimately became his hostage, she said.
"There were a couple of days I didn't have water or food. I lost 12kg in six weeks. It was semi-starvation."
She said he also expected her to pay for everything, including the household expenses and $20,000 to buy a car.
Her ex-husband has denied the claims, saying he never assaulted her and that problems in their relationship were her fault.
"In other countries the man feel the woman she don't respect him and I find that in her. It's not my fault."
