Williams later said he was never suicidal and the text messages were blown out of proportion.The text messages were released without Marzouki’s knowledge and “were taken out of context by the media. Ms. Marzouki believes that the media reports do not reflect the good character of Mr. Williams,” according to the statement.In his lawsuit, Williams had alleged that Marzouki never had any intention of marrying him and accused her of absconding with the ring and using the relationship as a means to get at his money.The lawsuit was filed a little over a year after Williams and Marzouki happily posed for pictures in the Bills’ media room once the team signed the free agent to a six-year, $100 million contract — the richest awarded to an NFL defensive player.In her countersuit, Marzouki called Williams’ claims “ridiculous” and “patently false” and said that Williams made it “abundantly clear in writing” that he wanted her to keep the ring following their last of many breakups in December 2012.
