You know, the biggest problem that people have when it comes to dating is getting out of their own way so that they can actually date and fall in love.
There are no "rules" about who should call, how often on should call, and whether or not it's OK to call often.
These are dynamics that are worked out between the people in the relationship on the fly. If this were a more open and actually communicative world, we'd be able to openly say, "Look, I like you, but I feel we talk too much on the phone and really I'm not so into that." And the other person would feel a little disappointed, but appreciate the honesty, and go on.
Just like the other person could say, I really like getting to talk to you every day after work. It's the highlight of my evening.
But, no, instead you people worry about calling too much, or not enough, or some random rule that you once heard about from a friend who insists that aliens are real and like to probe your anus.
Relax, every relationship has its own tempo and you have to feel this out.
