Kris Humphries Ex-Girlfriend Myla Sinanaj -- I Want Him Back!

Kris Humphries' freshly pregnant ex-girlfriend has lost her lawyer, dropped her lawsuit and is about to sign a confidentiality agreement with Kris -- the guy who tried to get her prosecuted ... because she wants to be back with him in the worst way ... TMZ has learned.

Our sources tell us Myla Sinanaj, who now says she is 3-months pregnant with Kris' kid, has decided not to go forward with a lawsuit she planned on filing against Kris with the help of her high-powered lawyer, Joe Tacopina. We're told Tacopina has already drafted the suit, claiming Kris defamed Myla by alleging she tried to extort him. We're told Myla has decided NOT to sue Kris.

To the contrary, as we reported, Myla has been in constant contact with Kris over the last few weeks, and he has been pressing her to sign a confidentiality agreement. And get this ... she's willing to sign and he hasn't offered her a dime. We're told she plans to sign in a matter of days.

Myla is telling friends she thinks there's a "good chance" she and Kris will get back together. Either that, or he's using her ... dangling a carrot so she'll shut up for good.

BTW, when we first broke the story last month that Kris was Myla's boyfriend, he changed all of his numbers so she couldn't contact him ... that is UNTIL she hired attorney Tacopina. Then he got back in touch real quickly. Now they're in touch all the time.
