My GF keeps calling me like 10 times a day at any time morning evening while im at college while im hangin out all time.she sometimes even calls me when shes having breaks in school and seizes any opportunity to call me.How should i use that to my advantage and how much should i answer and show myself hard to get ....etc.the prob if i dont answer her for a whole day for example she goes crazy and sends me messages asking why and so.THANKS
