Question . . . . did mike and kay actually get back together by the end of gf3?

And also . . .. this has been bothering me . . . what did mike do between GF2 and 3 to become so honored? I mean at the end of gf2 . . . he is just another gangster . . . a really powerful one. But still....at the beginning of GF3 . . . everyone wants to meet him, interview him. . . he is in the papers. What happened in the 60's and 70's?
Thanks!
