Cant figure out if this is a relationship or FWB?

I'm in agreement with the others that you need to ask him. I would also look for other signs of commitment. When he talks about long term plans/goals are you included? Also how does he introduce you to his friends? Does he talk to you about your goals or ambitions? Have you told him what you want out of the relationship? It is rather early in the relationship, so I wouldn't panic at this point, but I would start to look for clues on what he may or may not want in the future. Hope that helps. Merry Christmas!
