Expensive Perfume as a gift?

I work occasionally with a gentleman. I was able to get him some extra money on his paycheck due to some unposted payments. He bought me a very expensive bottle of perfume from Creed as a "thank you". There seems to be a lot of flirting on his end, but pulls back frequently, then he's back on again. He also talks about our working/business/investment future a lot. I totally have a huge crush on him, but I do my best to keep that to myself. Should I consider that he might really want more than friendship or could he really just be saying thank you? He's got me so confused some days. But the perfume is so luxurious and intoxicating. He mentioned after I put it on that the undertones f**k with your head. Thoughts? Someone please help me figure this out.
