Smoking marijuana. Do i have an addiction?

So for the past two weekends now, i'v bought marijuana. This isnt a normal thing. I use to smoke alot back when i was a young teenager. I usually smoke socially now, but since i'v bought the bags [FYI-i bought some because i was in the mood to smoke more than socially.]
I dont usually buy much. Just worth, which is a little bag. And it usually only lasts 2 days.

My boyfriend says im addicted to it because i "cant NOT smoke it"
But i dont think i have an addiction because i dont feel like i HAVE to smoke it. I WANT to smoke it. I enjoy the high. So what.
Does this make me an addict? He says im in denial, but how the f* is it an addiction, if you smoke it because you enjoy it, not because to HAVE to have it?
Am i in the wrong when i say i dont have an addiction?
