In life sadly things not always works in a way we wanted or hope it should be, i understand your feeling and it must be hard , but if she can do this without you you also can do this without her, you know what i meant, everyone deserves to be happy including you and the only thing to make that possible it need to start from you...i am not saying its gonna be easy but if you work hard on it its possible..

And about Facebook, all the people who sounds and have this happy status not always have a happy life, sometimes they just want to sounds happy to cover up their lonely life ...believe me i know someone who like this ...she seems like she always on holiday and have a nice life but unfortunately i know her and i know she is depressed and ect ....Facebook to me its like popularity and showing off contest so dont take it personally
