There're so many rules like if he didn't call you, he's just not that into you etc and so many signals like he said it's good to hear from me proves that he likes me. But all of these have excptions. He may call you at the first time and spend lot of time with you but actually not that into you yet on the contrary, he may not try to call you when you need but he indeed has crush on you. love is eternal belief and tolerance. BTW this is not an excuse for a liar. girls open ur eyes, stupid girl doesn't deserve to be loved.
