Y do men lie

I ask and asked myself this question over and over again why do men feel the need to lie why come on a site, pretending to look for love or that ideal person to settle down with and once you respond fine you chat thinking this is the guy for you, but to your determine your hopes is quickly dashed he does'nt come back to you the day after tomorrow all you talked about flies out off the window now I ask myself why they do it plain chicken that's y they scared then why you here why not just leave everything y play with some ones feelings give them hope and then stampeding all over it,its the most cowardly thing to do we come here to look,find'hope that some one out there might spot us not for sheer fun out of desperation nobody wants to look so desparate as to openly advertise ones self but the need for companionship the loneliness drives us in the hope of finding that prince charming its not a galant thing to bruise that hope why then I ask are they doing it they toy with us butter us up some even seem so sincere,hope nobody treats you that way ever its heartsore humaliating and a loss of ones self esteem makes you want to give up hope when actaully hopes so near why why why then guys.
