Well, its not fair if u dating her out of pity talk less of getting married to her out of pity. It seems u were playing tricks with the girl's emotions and having fun, now wat makes u think wen u get married to a beauty queen that u guys are gonna have gorgeous kids. In a nut shell u never had plans for her from d very beginnig, for a whole year u guys dated and am sure u didnt look at the ugly side of her before kissing and getting down with her. If u know deep down with in  u that u cant spend the rest of ur life with her, let her know and look for some reason to of letting her go, cos its not gonna be fair to tell her u breaking up becos of her looks and to ve wasted a whole year. Think about it well, remove sentiments. and remember, U cant have it all.
