I think other women would feel exactly the same as you do, and now the 'scales have fallen from your eyes', so to speak, you're now feeling more than just unfulfilled, you're deeply resentful. You feel (rightly) that you have been 'hanging on' for years, hoping that he would ask you to marry him.
You have finally come to accept that he was never going to, and you are, of course, upset about this. You feel angry at him, but also at yourself for being 'fooled' for over a decade that this 'relationship' was the real thing and would eventually end in marriage.
There is no set 'time' when someone finally realises what others outside the relationship have known for years. You probably had entire years pass without really giving it much thought.
But now that you have realised that he's never been interested in getting married to you, you cannot return to 'business as ususal' or 'unsee' it.
It doesn't matter if he has nowhere else to go, remind him that he's had over a decade to get some money behind him
, so if he's got fuck all saved, that's his bloody problem, not yours !
