what's wrong with love at first sight

I'm generally asking. isn't the best part of a love affair when you began? it's at this time that niether party has found fault with the other and the hope is 100%. when you get all them flushes and goospimles at the ring of the phone, when you can run out of what to say on the phone but still refuse to hang up but just hold it there at your ear and sigh. it's the time when you wonder what's wrong with your belly and someone ask have you eaten since morning and you gasp "oh my God, that's it". does love really grow? after years of mounting stress year after year finding out the little lies that adds up and the bad habits that won't go away? and if the love does grom what is it rooted on? what waters it? how is it discibed was it because or inspite of.
