#2 Never show that it bothers you
The biggest mistake most women make is to whine “but why didn’t you call me last night/yesterday/every hour?” To clobber him with questions is only going to push him away rather than make him love you more. A wistful “but you used to do it before…” is even worse. Remember, men hate questions about relationships all the time.
In the beginning of every relationship, hormones are on overdrive and that would make him want you all the time. And without even realizing it, he would want to spend every waking moment with you. But a relationship, like everything else, is progressive.
