Getting the spark and love back!!!!!!!!

Hi so me and my girlfriend have been going out for about a year and a half....weve just had a bad month full of arguments and shit...prior to this month she would text me quite abit saying i love you lots etc.....but now some days she doesnt even text or ring me.....i know it takes time but im wondering if theryes anything I can do to get the spark and sexiness back? i meen i know she still loves me alot but shes not as hooked shall we say on me atm...what do you girls like to here on texts? what should i do? should i just not text her when she doesnt text me? play the guessing game or what will she want to hear?

what will get her back to texting and ringing me with these nice things to say etc...thanks

up............
