It's perfectly natural to miss your boyfriend, but it does sound like he prefers to be out and about. Do you have any other shared interests? Maybe shoot some hoops with him and his mates, or play some ice hockey, shoot some pool at the pub, do martial arts and beat each other up?

In any case, it was rude to blow you off on a virtual date like that sis. If he keeps throwing how you feel back at you, maybe you need to draw a line for how you want to be treated. If anything, a quick, "hey hows it going, ok have fun!" type of phone call may satisfy you when you don't see each other. If that doesn't work, it might be a sign you're drifting apart.
