It was the kind of relationship that allowed Ronnie-Boy to impregnate some female to give birth to not one kid, not two, but triplets.
What Alti did on her side... She may or may not tell us about it.
There is no indications that she's been swinging around though.
The fact that Robert Lopez and others are lap dogs at her feet, would indicate that she didn't.
That's because they were waiting in the wings. Almost any guy friend would smash a hot woman friend, if given the opportunity. With Rob being a DJ and not being able to get his pro card and Ronnie being MR. O and a former police officer, Rob, just would bide his time. You don't f with Mr. O's girl, especially if you have a lot of respect for him, unless you were effing with her, but making it seems like you are the best of friends...ANd then come out profess your unduly support for her.
But as you said, we don't know what Alti was doing on the side, and a lot times women do a lot more than the men, they just are better at playing the victim.
