Friends with benefits, yay or nay?

I dated this guy we broke up but we stayed friends but now lately it's like we are more than friends but no commitment. I still have feelings for him and I've made that clear but I also don't want to jump into another relationship just yet seeing as I just got out of one 2 weeks ago. Am I making a mistake? Should I stop things before they go any further or should I just go with it?
