Weekends only really shouldn't be that tough for him to handle, especially since you do talk on the phone daily (or nearly so).

Now, he's told you that he tends to get cold feet early on in a relationship. Did you ask why? Is he afraid of commitment? Maybe he's one of the sort that doesn't think he really deserves a great relationship and, that becomes a self fulfilling prophesy for him?

The other thing to remember, and don't beat yourself up over, even if it doesn't work out: It's called falling for a reason.
