Re reading and listening to some of the things other actors have said about him at that time,it seems he really was completely besotted with Matilda.
It would appear he never lost an opportunity to either talk about her or pass photos around.
I can only guess how incredibly hard it must have been for him to be parted from her, particularly at Xmas. I can think of no parent who does not want their child around on Xmas day.
Leading up to the holiday season, he certainly was looking more haggard,but then I suspect he was tired and depressed.Fame never seemed to rest easy on his shoulders.He was also incredibly analytical about his performances.Always feeling he could have done better. Had he been around longer,he may well have ended up more behind the camera than in front of it.
It was I think his personality type to have bouts of endless energy, but also times of depression.He certainly always seemed happier and more at ease when he was with "real" friends or a girlfriend.They seemed to give him the support neatwork he needed to cope with the paparazzi and endless rounds of promotional interviews. I do not think Heath was very good at being on his own.
He may well have dabbled in some recreational drug use, but then that seems to be pretty standard, for the world he moved in, particularly after he became single again.When he was with Michelle and Matilda I suspect he managed for the most part to remain more grounded. His attire may have been not to everyones taste, but he still looked well and happy.
I truly believe he was a genius and not many who have that word applied to them, are happy within their own skin.The pursuit of excellence can involve plunging down to the depths of your soul, and finding some very dark places.Surely that is why he tried to alternate lighter movies, with more challenging ones.The phrase tortured genius, is very much grounded in fact.
The other inescapable fact, is that when you are famous, there are always going to be "friends"/hangers on, who will proffer all sorts of recreational substances, in an attempt to curry favour.Heath needed real friends, not false air kissing ones.
Whatever the truth of the matter is,the inescapable and desperately, gut wrenching fact,is we were deprived of him, far too soon.
What gave him too us ,may have ultimately destroyed him.
