Can this friends with benefits relationship end up being more?

Were both pretty good friends. We hook up because we have great chemistry and really care about each other. During the year we've been having this relationship it's been very off and on, usually with me being the one to end it. Even the couple of times he has ended it he always calls me wanting me back. And even when I've ended it I've done the same. During this time I've dated a couple of people (this is when I would end things with my fwb.) He has not dated or slept with anyone Else the whole year we've been off and on. I do care about him, and we are great friends, but I'm curious as to if a relationship like this can develop into the boyfriend girlfriend kind.
