Its tough to say because it has only been 3 weeks. Its too early to say. But I would not stress over it too much. Just try not to be too much after him, or calling him, give it sometime to see if he tries to call you and contact you, this way you will see, if he is putting any effort into trying to contact you and get together with you. In the mean time go out with the girls to keep your mind off him. If a week goes by and there has been so little effort or none at all to contact you, then i would say he might not be that interested. Time will tell.
Christy Murphy is my favorite comedian she's pretty good,cute,awesome and hilarious
