Friends with Benefits Options

[loveneko]

A friend of mine and I are friends with non-sexual benefits.
We've been together on and off for 2 years and a lot of change. I got with him freshman year of high school 2005, left him and started dating my ex Dec 2006, he and I were still friends with benefits until Jan 2007 then I cut him off completely and broke his and his family's heart. I broke up with my boyfriend in Oct 2008 and started talking to my friend with benefits that same month. (He was afterall my friend)

My friend with benefits and I went back to our old ways in November 2008, and we've been like that ever since.
We want to take our relationship to the next level because the fact that I wasn't his girlfriend is one of the reasons I started dating my ex-bf in the first place.

However, we don't want to go out with each other, because he's weird and stupid. He becomes unfaithful when he's in a relationship (I dont know why, he's just so silly) and I dont like to share my boyfriends with anyone (which he does to me, but it's a problem when I do it to him).

I really want us to start dating, and he always complains about me keeping him in the friend zone, but I'm not, he just can't control himself and I dont want to get hurt.
We practically are going out, he calls me everynight, we hold hands in the streets, we show PDA (public displays of affection) he tells me where he goes when he goes and who he talks to if its not me, but I don't. He gets jealous, but he always says, "its none of his business" blah blah blah. Whatever.

Should I just tell him to shut up and go out with me already?
