I think that you should give him a call. Ask how how he has been and ask him if he's interested in together (as friends) sometime. Then proceed w/ the relationship from there. No, i wouldn't think that you are stalking the guy, all you're doing is calling him, it's not like you are showing up at his house 24/7 or calling him every minute of the day. So i wouldn't worry about tht.
So go ahead and call him, ya never know what might happen, you might regret it if you didn't.
