Have you ever fallen for a girl whom u believed was perfect for u and known her for only 1 week??

she tells u everytin u wana hear.. she tells u u give her erflies.. then afta u meet up and kiss n all.. few days later she goes cold turkey.. when accused she denies it and uses excuses like i get bizi at times.. my fone hasnt been workn properly..altho u kno she can use a landline 2 ring u for example. how do u get ur mind off her? .. she tells you tings that u feel sorry 4 her.. and she cn turn around n say no dw nutins changed promise but dusnt return ur calls or msgs for 5 days strate... i feel shattered!.. the same week i met her.. i leave my gf of months.. altho she was good 2 me n everytin.. i felt no bonding with her.. now ive left the 1 that was good 2 me.. and the 1 i cnt get out of my head.. is js cold twrds me.. however i do emphasis.. i didnt leave my gf 4 this 1.. i was plannin on 2 4 a few weeks its js happened all in co incdental timing.. im prob sound like a broken record.. but thats exactly how i feel... i dunno what 2 do..
