Cho didn't like Ron Weasley and Hermione Granger; she believed that Harry had romantic feelings for Hermione, instead of being friends. This was one of the reasons that Cho and Harry fell apart.

Ari Ron seemed to be most effected by the locket Horcrux. He left because it intensified all the negetive feelings he already had: Jealousy at how easy Harry and Hermione's friendship was, hunger, frustration, fear, desperation, his quick temper and tendency to jump to conclusions, concern for his family...
So of course it's natural that Ron feels jealous of Harry sometimes, as we've seen. But Ron has everything that Harry wants: a loving family, a home, parents that love him, growing up belonging in the wizarding world etc.
