Yes, Aidan is being "kind of dumb", but it might even be on purpose, he knows he will easily fall for Heath and is protecting himself, thinking Heath is too much of as playboy to be worthy even considering... So Heath can also grow some balls, be the older and more experienced one, and talk clear and plainly to Aidan. He keeps trying to get Aidan to meet him half way in the understanding, but Aidan is too guarded for it, in the end, Aidan is growing, but Heath will grow more.
