First, I want to make sure I'm clear on the point you're trying to make here. It sounds like you're saying that a film/book about Motley Crue (which you acknowledge is probably exaggerated) recently reminded you that Richie and Tommy Lee chose to marry the same woman; and you think that supports an impression that Richie has never been very mature.

If that's what you're saying, there are a few things it seems you may have failed to consider:

• Heather's marriage to Richie bore little resemblance to the volatile relationship she shared with Tommy Lee.
• As steel_horse75 said, Jon didn't like Heather. But the only reason I heard him give was when he told Howard Stern that she kept Richie on a short leash (which only made him less of a party-guy, at least away from her) while she did whatever she wanted. Then Howard insinuated that Jon's resentment actually grew from the fact that she took Richie's attention away from Jon (and the band), which Jon denied. Of course.
• When they split, Heather and Richie agreed to put aside any differences and maintain a decent relationship so the divorce's negative impact on Ava would be as minimal as possible; a decision it seems they've stood by to this day, despite any mental or substance issues they've had.
• During his marriage and after his split from Heather (or any of his ex-es) Richie kept the details of his private life out of the press as much as posdible; and refrained from placing blame or publicly trashing his ex-es. Even when Ally Sheedy and Nikki Lund made accusations, he simply denied their allegations, handled whatever needed to be handled, in private, and kept his mouth shut about anything else. Some people may see his silence as an admission of guilt; but it seems to me that he's just standing by the decision he made a long time ago to keep family business in the family.

Sounds pretty mature, as far as I'm concerned.

In fact, aside from Ally, Nikki, and Lehua Reed (who allegedly warned Heather not to marry Richie), out of all of the people we've heard from through the years, who have been the closest to Richie and should know him best, the only ones I've known to make comments that might indicate he lacks maturity or acts irresponsibly - in either his personal or professional life - have been his former boss and one of his former bandmates.

(But stay tuned. From her recent posts, and snippets of her new songs, it wouldn't surprise me if Orianthi takes a page from Jon's book and uses Richie to promote her new album the same way Jon did with THINFS.)
