Help me with this aries man

Hey you fabulous human beings, please help me with this certain Aries sign.

Here's the story: There is this Aries guy in town, he's Canadian and here to work. I added him on facebook and since a few weeks we chat around a bit. I have also met him, but in his workplace and together with my boyfriend. But since a few weeks I somehow can't get this Aries out of my head. We chat but I don't really get if he's intersted in me. Would an Aries even try to go for a girl who's in a relationship? And another thing: i don't know if he has a girlfriend, he had one before he came here to work, and there's no sign of affection to this lady publicly on facebook, but she's visiting him in a few weeks. Would and aries keep a "friend with benefits"? And I'm a leo and too shy to ask him out since I'm afraid I could ruin the friendship we have. Should i let him come to me or shall i make the step forward?
Thanks for your help, which is really appreciated!
