It really sounds like it is time to say "NEXT" and walk away from this Aquarius man.
He is clearly showing you that he is not a man you can depend on in a CRISIS -- and it is fortunate you have learned it now.
Of course you can make excuse for him about how shy the Aquarius man is blah blah. This goes beyond shy. This is failing to come through for your woman in a CRISIS.
I will be thinking of you.
