How do i settle this???

There are something things that many are willing to search in order to discover whilst others sit back and something hits them and they discover.... what do i mean by discover?? I mean see the world from a whole new perspective... Recently i have discovered such a wonderful world.. everything seemed great, skys were blue, life was fun and everything was going so well .. but really all this was because of the feeling that i thought i was falling in love... but little did i know love would come with such great consequence, it comes with hard break, insecurity, worrying and most of all fear.... Hey at first everything was going fine especially after the first time i saw the person it becomes so obvious that your attracted to them and their attracted to you.. but as time progresses things begin to shift and change , the world of mine seem to become to hot at times or to cold, the sky is to cloudy and the littlest things can set ur anger off.... the person you want to be with already has soemone else, u still want them but u've now become insecure and ask yourself " do they really mean what they say to me when they've said they've lost feelings for the other" its so hard...
i stare at my fone for the past hours hoping that i would recieve a call... 1 hour pass.....2 hours passs 10 hours pass.... nothing not even one simple missed call... makes me think back to those days where they would simply call just to say " i miss you".. nowadays i just crave for a hello on the fone... so i give them a call ... normally they would always pick up but nowadays it seems to ring endlessly.. ring ring ring ring ring ring.. then to the message box.. maybe they've gone back with their lover who they have claim to have lost feelings with... but i have told the person to try and rekindle with their lover maybe i was just being to nice, or was i just trying to mock them??
sometimes i feel like i am asking for too much... but am i?? i just want a simple answer from them do they still have feelings for me or has it gradually being lost...
but do i really want to hear the answer.. wat if the answer was no , would my insecurtiy just tell me that they are lieing to me, or would i just happily smile and kiss them to show them that i too havent loss any feelings... or what if they were to answer me yes they have lost feelings ... do i tell them well i think its best for me and you if we stayed friends and that i rather not try anything for i know it would turn to a one way love way....
Its so hard.. i dont know how to stop these thoughts... i cant stop thinking... i cant sleep, cant eat, just watiing for them to call me so i can ask the question....
Love is such a harsh thing to go through if its a one person thing but if there are two people in love i guess thats different.. but why am i always never the rule of two but the exception of one ... It hurts it really does....
