Ric Flair's latest marriage has officially hit the mat -- his fourth wife has filed for legal separation ... claiming the legendary pro wrestler was as big of a cheater in their marriage as he is in the ring.

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. 

Ummmmm am I missing something here Jackie? Listen sweetheart I'm not sure what your game is here but marrying The Nature Boy Ric Flair and then divorcing him because he's stylin' and profilin' is downright insanity. It would be like marrying Aaron Rodgers and getting upset that he works on Sunday's. Or marrying Mel Gibson and filing for divorce because he goes on anti-Semetic rants. Or getting engaged to Magnum PI and breaking it off because he won't shave off his mustache. Like these are all package deals. Asking Ric Flair to be monogamous is like asking Superman to walk from place to place. Just doesn't make sense on any level. So in my opinion this should be the quickest divorce proceeding of all time. Just no way Flair doesn't walk away from this scot free. Strut into the court room in a bedazzled robe, play the above 19 second video that basically laid out your life credo 30 years ago, walk out with two random chicks and let loose a WHOOOOO! as you exit. Ric Flair 101.

PS: How about this comment on TMZ's story:

If this isn't the epitome of internet tough girl-ing I don't know what is. Listen Floridagirl, I'm sure you think you're being cute and funny on a comment board but I guarantee you if you met Ric Flair in person you'd be on Space Mountain faster than you can say WHOOOOOOOOO.

Double PS: Ric I know you've fallen on tough financial times but I'm here to promise you that I'll do whatever it takes to work a WHOOOOO! into every break I have until the new year. We'll make up those tens of thousands of dollars 12 cents at a time.
