Am i being silly to be upset about her Past ?? :/ Cnt jst forget it ! Any suggestions plz ? ?

It is common for someone not to let u in on everything until they are confident in you. This is a case of a lady trying to find a decent life out of her past. She needs to stop her silly habits of flirting around and smell the cheese - she has got the bf she needs so get on with it. As for you forgive but dont forget. Her behaviour hereafter will determine wether time will make u forget or not!
