This question goes to you, GS Girls:p(and if you were a guy assume you were a girl ok?)
What would you do if one day your best friend called you crying so bad and told you that the she’s found out that the person she loves (assume you didn’t know his identity before) was cheating on her
and then came the surprise
she tells you his name
this guy is the one you’re involved in a relationship with and so much in love with!
how are you going to react?
Who are you going to choose? your love over your best friend? or the opposite?
For me it's a very simple answer, if someone lies and hides things from you, then it's over. There's no second chances. I'd never be in love with a guy if I don't have absolute honesty and trust.
Rather then worrying about who to choose, i think you should be re-evaluating both your friendship and getting rid of the guy. U decide your own worth by the people you surround yourself with.
