On a slightly more serious note for a minute........
The (thankfully few) posters rambling on about Jack's 'bad behaviour' - and how 'if it was middle aged men lusting after a 25 y.o. woman you'd all be calling him a pervert' can bore off! 
So, Jack isn't squeaky clean, and is not perfect. Show me someone who is. The people acting like their shit don't stink; slating him for being a 'bad boy,' in the past; I bet YOU have done some questionable things in your past.
Also, it's ludicrous to say middle aged women fancying a gorgeous 25 y.o. MAN (not a young boy like some twit said further back,) is 'inappropriate' and imagine if it were MEN saying the same.
Reason being, if a middle aged man fancies a 20-something woman, he is more likely to act on it, and try it on with her, letch at her, and think he has a chance with her. Because some (not all,) middle aged men fancy their chances with women 20-25 years younger, and genuinely think they will be interested (LOL!)
A middle aged WOMAN who fancies a man 20-25 years younger, is very unlikely to act on it, or try it on with him, or letch at him, or think she has a chance with him.
So don't even TRY to compare middle aged women fancying a younger man, with middle aged MEN fancying a younger woman! The two are incomparable.
