BUFFALO, N.Y. -- Bills defensive end Mario Williams isn't any closer to getting back his $785,000 diamond engagement ring from his former fiancee, Erin Marzouki.

And Marzouki's attorney, Tony Buzbee, upped the ante on Friday by releasing a series of text messages he said were between his client and Williams that indicate how despondent the player was over their breakup in November.

Without going into detail, Buzbee said in an email that a court-encouraged effort to mediate the dispute was unsuccessful in Houston earlier in the day.

Accusing Williams of experiencing "dramatic mood swings" throughout the engagement, Buzbee also released an exchange of texts between the two he said he copied off his client's phone. It's a conversation dated as occurring between 4:51 and 8:26 p.m. Central Time on Nov. 11, and includes a break between 5:03-8:02 p.m.

During the exchange, Williams wrote: "No money in the world should leave me with suicidal thoughts."

Williams also wrote that he took three hydrocodones that morning -- that was the day of Buffalo's game at New England. And he planned to take two more on the plane home. Hydrocodone is classified as a narcotic, and prescribed to relieve moderate to severe pain.

Marzouki responded by urging Williams to get help.

"Why don't you talk to someone? Clearly you're not happy & if your takin pills that's bad," she wrote.

Williams apologized, and then wrote he agreed with her that he's furious and should not have texted her in "this state." Williams added: "I need to go back n my shell. There's no telling what Ill do to myself at this point. I'm sry Ill disappear from now on."

Messages left with Williams and his attorney, Monica Orlando, weren't returned.

Williams did post several notes on his Twitter account Friday night -- among his first since July. Though they didn't mention Marzouki or the lawsuit, the messages posted were in defense of his character.

"I'm still here and always will be," Williams wrote. "I'm too strong for ridicule and the childish extremes those will do to try and taint a persons name when in reality you make me stronger, hungrier and more determined."
