Security

you're right in there, bokal. Women are generally wanted to be pampered, even those who are not telling it verbally, but inside they want it. That simple message of endearment would be a great way of showing that they are special. But in fairness, I know some men are also amorous though, being men, they don't want their soft part be known. But I think if a man loved a woman, it will come out naturally without being aware of it.

Security? What kind? I think you are talking about emotional security. Women sometimes tend to be so demanding to their lover. They wanted to be noticed and loved most of the times. I'm also a woman and it brightens up my day if my husband would send me sms just to say how much he loves me and misses me... and how long he wanted to come home so he can embrace and kiss me. Maybe girl's like their lover to be as thoughtful as possible, not to forget special occasions and always very showy of their feelings. But as I said many times before, it really depends on the two people involve because there are lots of guys out there that is not showy or expressive on what they really feel.

It's because they know if something bad happened, the girl will know, and if she doesn't get the text, then it means the man is okay, and he is safe. Plus it takes 30 seconds to write text saying 'I'm okay and I am home'. So you know, the laziness. =))
