During the season, this changes. Jionni begins to act in a manner that can only be called jealousy, showing he does not trust Snooki. Jionni becomes very controlling and wants Snooki to stop drinking, to stop going out, and basically to not go out. 

After returning from the bar really drunk one night, Jionni starts fighting with Snooki really hard on the phone so Ronnie takes it from her. When Ronnie gets on the phone, Jionni tells him to "go fuck off."  The next morning, Ronnie tells Snooki Jionni was "being a dick" and that she "didn't deserve that."

It has become apparent, the roommates believe he's a "dick" that wants to change Snooki, and the roommates think it is wrong for a guy to want to change her. They believe he should take her as she is, for who she is, and for what she has to offer. JWOWW directly states that Jionni isn't the guy they thought he was and instead isn't a good guy at all.

I think it is time for Snooki to move on and find a guy that treats her like she deserves to be treated. I would never stay with a guy if he talked to me the way Jionni talks to Snooki.

What do you think, should Snooki leave Jionni even though she believes she is so "happy" with him?
