Why are good men so hard to find?

I met this guy about 3 weeks ago and we hit it off fine. Now he's not as attentive as before and he hasn't call me in 2 days where as he used to call me 2 to 3 time every day. It's not because our relationship hasn't reach that level, mutual agreement. What could have made him change and I notice he's bought a webcam. Could it be that he's found a new interest?
