I don't think Joe is necessarily "jealous" of Niomi, but maybe yea a bit resentful that she still has her career (he doesn't), is living where she wants to (he's not) and probably makes more money than him. Not that this was the direct cause of the breakup, but guys have fragile egos and maybe combined with other things it was enough for him to let it go. I just doubt the break up was JUST over her controlling nature... he's known about that for a while. It had to be other circumstances.
Also on the whole Woodward thing, I do think it's weird that they've never been in her videos at all or barely even mentioned. It's probably for privacy and I totally get/respect that, but it seems odd that they wouldn't be more supportive of their future daughter-in-law's profession. It's not like Niomi talks about really controversial stuff... would it kill them to do one video about lifestyle or health or something? I mean Joe's dad was in sport.
