Hi
Some women like to play 'hard-to-get' and may intentionally ignore your phone calls. If a woman doesn't call you, it maybe time to exercise some initiative and make the first move. She might ignore your phone calls, forcing you to use the answering machine and leave her a message. Some women try to retain their modesty and they don't want to appear needy. Some women feel that returning the call will make them appear desperate and lonely, so do not expect an expedient reply.
Thanks
