Pro Wrestler Ric Flair's Wife Files For Legal Seperation

Jacqueline Fliehr filed the docs in Mecklenberg County, North Carolina earlier this month citing "acts of illicit sexual behavior."

In the docs, obtained by TMZ, Jackie explains, "Husband has had numerous intimate relationships with other women during the parties' marriage, to the embarrassment and humiliation of wife."

Jacqueline also notes that she was a "faithful and dutiful wife" ever since they tied the knot in 2009.

But there's more ... Jackie claims Ric has totally screwed her out of tens of thousands of dollars in spousal support he agreed to pay when they hammered out a separation agreement back in October.

According to the docs, Flair agreed to pay Jacqueline $4k per month in spousal support ... plus a one-time payment of $15k to cover legal costs. He also agreed to pay $14k in back payments from the time they split in July.

But Jacqueline claims Nature Boy totally blew off the agreement -- and hasn't paid her one single cent.

Now she wants a judge to force Ric to pay up ... which shouldn't be too hard, considering she claims he still makes more than $1 MILLION per year. Not bad for a 63-year-old pro wrestler.
