(For women only) What is smothering? What is neglectful?

I've been told by a girlfriend [age 23] who I called twice a day, that I was smothering her (the same one who complained about men being neglectful and playing games) Likewise, I've been told by another girl [age 17] who I called every two days, that she didn't think I was that interested. Is this an exact science or what? Should I space my calls between 24-30 hours apart (sarcasm)?
