Dos and don'ts of a relationship ?

just be very practical, and as u said u r just his girl friend than just be that, give urself lots of time before u plunge into the love again, cause u cannot afford to hurt urself again. he might be the good guy, but at the end of the day it is you who will suffer the most if relationship does not work out. give ur relationship a year atleast to mature and know each other properly till than dont get too serious. trust me it will help u. good luck
