Should I take the lead with this Scorpio man?

by piscesgirl

I've been talking to a Scorpio for about 2 months. He calls me maybe once a week and we talk 2-3 hours. He's really difficult to read, we've never once talked about "me and him", just random (sometimes deep) topics. We've been together only three times, and I want to know whether or not he's interested in me. I'm already vulnerable to him, and it's very unusual for that to happen when i talk to a guy. Should I ask him? should I call him? He also once asked me if i "expected" him to call and if i liked it when he did. After i said yes, he told me that sometimes he doesn't call because i may be busy (but in a way he seemed to mean it like he was unsure if i wanted him to call me). Is he insecure like many have told me? or is he just testing/playing games?

Take into consideration: He's muslim, and has told me that he doesn't know how to let his parents know he would like to talk to girls outside his culture.

Oh, and I'm a Pisces.
