I have two successful kids, both with kids of their own and I see them as often as possible.
I like to hunt, fish, play golf , and go hang out with friends for dinner and drinks.
I, like you, have come from a "busted" relationship, we all have and all I can say about that is, "Get over it", regardless of whose fault it was, it makes no difference now.
And I, like you, are looking for that "spark" again, that feeling that you can't wait to go be with "that person".
As far as whether the glass is half empty or half full, my feeling is that if your glass is less than half full, we need to open another bottle of wine, ok how's that ?
So, it's pretty simple....I'm a "Normal Guy"
