Acted on it; Acted upon - Tradução em português

I slept with a very good friend of mine, several times. When we were growing up together I had such a crush on him and he had one on me, but we never ever acted on it till we were in our 20s. I think those residual feelings are what I acted upon, but I realised after a while there was just no spark, for me – in truth I am just not attracted to him any more.
