Can anyone help me??? suggest some pills or hairspray?//

Nothing will grow hair where hair isn't already growing. Hair growth as well as amount of hair (regardless of where the hair is on the body) is ALL in your genetics. If you didn't inherit a 'hairy' body from your parents, you cannot achieve one with pills, lotions, potions or sprays. You could possibly achieve a hairy chest with a hair transplant, but I don't think that is feasible.

If your girlfriend truly 'loves' you, the amount of hair on your chest shouldn't matter to her or to you. Besides, when a (bodily) hairy man sweats, he smells much worse than a man that has little body hair. Give me a smooth chest every time - and I say that even though my husband has a fairly hairy chest; not much on his head, but on his chest, his rear-end, etc. He only smells good in the wintertime when its cold outside and he isn't out there working up a sweat. In the summer, he smells like a wet dog all the time.

I say, stay the way you are - if she loves you, she will love you without a hairy chest.
