No man is really busy, only your status in the heart is big enough or not.
No one works 24 hours without spending time with the woman they really love, no time to send a message asking "Are you back?", Or no " You alright".
General rules, men are heartless, simply their minds are located elsewhere. Men really love their woman, instead of saying "I'm busy", they will say "wait for you". In the same sentence, they will say wait with the woman they love, and say busy with the woman they are bored. So do not mistake the mind is nature, without heart is simply out of love.
Men are always greedy, but in general they can not hold everything themselves, so someday, if they have replaced. It is imperative that they speak with one person, to spare time for others. So when the men speak, it is a sign of change.
