LOVE ADVISE NEEDED? PLZ DO REPLY.......PLZ

HI,its kamal here.in love with a gal for more than 5 years.and now i need help from all of u.i am new to this site and found that ppl were really helpful and nice.plz do get time to read this and help me.thanks in advance.

              i saw a gal 5 years ago,may be it was love at first sight.i juz loved her everything.soon after, i proposed her bt she juz ignored.i juz cudnt help it and took 20 sleepin pills and was unconscious for 4-5 days.when she found abt all this then her feelings grew for me.bt coz of her strict brother and family we werent able to talk much.we used to talk to each other 7-8 times a month over phone.no personal meetings though.
                   i wud like to tell again that i juz love her everything and juz cant imagine my life without her.i know even she loves me bt now the problem has arised.from the last few months we are talkin to each other a lot more.and i am damn sure she loves me bt i dnt know why her behaviour towards me is always rude? when evr i ask her smthing she says I DONT KNOW OR WHY SHUD I TELL YOU??? her behaviour is always rude and all this is disturbing my life a lot. bt she also says that she will marry me only.
                    so,i decided to change my behaviour also,thinkin that she will get to know about my importance and will change herself.bt i juz cant hurt her in any case.coz i know she will have tears rolling if i behaved in a rude manner.
                   WHY DO U GALZ DO THIS??PLZ ADVISE WHAT SHOULD I DO? I DONT WANNA LOOSE HER.I'D BE LOST IF I LOST HER.PLZ HELP ME GUYS........!!! iI WANT ALL OF U TO GIVE SUGGESTIONS.PLZ PLZ PLZ.
