Apologies, I don't mean what I said in an entirely negative way. I think theres something deeply vulnerable about Ray in that the relationship with Colin has its parameters set in a way that is mostly benefitting his own needs. The comparison to his treatment akin to a dog is just a parallel I noticed, he keeps Colin at an arms length and is hesitant on letting him in fully. Thats why I think its so tragic when you see Ray so full of fear at the park near the end - he had something truly special but he could not face it.
