Do these actions speak louder than words?

I have a crush on my guy friend but he never wants to verbally express how he feels about me, even though his actions show he likes me. There have been situations where he acts out of jealousy (like if another guy friend talks to me, he'll bring it up) and fear of abandonment (he thinks that I'm going to leave him), when there really is no reason for him to. Do you think these specific actions show that he has feelings for me too?
