Mampakha........naam jastoe vhaya ni kura vhanay thik garnue hudeo raicha. Absolutely agree with you; although teyo formula chahi khai kahilay dekhya koe thina....thaha paya khusi lagoye.

Love comes from Pleasure. (I am not defining Pleasure here as a act of only making sex or intimacy). Anything that brings happinees and sense of fullfillement and also things that you wish to do is simply Pleasure. As mampaka said Sex, Touch & Intimacy is human need ( we know few expactations...thats why they are excpetations; not the normal way of living standrad life; they are special as many things have). Besides, there are other chemical reactions and hormones alterations that alters mind and body.

The biggest fear comes from loosing things or persons that brings pleasure to you. While some ppl (very few) in the hope of reaching these- "things or persons ",  do everything on their power to control. however, with time, these fear and hope grows and ppl tend to look for other alternatives. I am not telling that these long distance realations doesn't work. They do, but to very few ppl. But @ somepoint the "need" overcomes your "determination". this somepoint varies greatly with individuals.

In simple, any relationship is like a "growing seed"; a constant attachment and nourishment is essentail for healthy growing.
