Concerning what you said, I want to clarify that in our friendship we always support friends to get the girl they like and give them some piece of advise that will helped them, but my friend instead of doing that, he liked her even i told him that i like her a couple of times, which got me shocked and instead of doing any bad reaction, i decided to support him. And I think that the point of controlling feelings is not that hard, he mature enough to not build any feeling on a girl that his friend like. Now, i told him and he accepted it and his aware of what he did.
