Tareq Salahi -- I'm Divorcing that Bitch!

Tareq Salahi has had his fill of humiliation ... we've learned he's filing for divorce.

TMZ may have jogged Tareq's memory a bit when he saw video of Michaele and her lover, Neal Schon kissing -- a video HE SHOT over Labor Day.

We've learned Tareq is telling friends he can never trust Michaele again and will never take her back, even though he believes she'll eventually tire of Neal and try to come back to him.

We've learned Tareq has already changed the locks on the family homestead and the winery.

Looks like Tareq did stop believin'.
