How do I get him to see me as more then a "mate" with benefits?

Long story short. We are friends with benefits but he said he sees me more as a mate then anything else. How do I get out of this "mate" zone and become more of someone he sees romantically. Will being more flirty help?

Not here for a lecture on how I shouldn't sleep with someone without the commitment etc first.

Probably should have added that we didn't start as friends with benefits, we were starting to date each other doing all the couple things etc then he just distanced himself and it just progressed towards what everyone would call a friends with benefits.

Also should add, I don't think he understood how I felt (he does now) and I think he assumed I was happy with just being friends.
