Starting off by accepting the fact that If you can't have that person in your life then it must be for a reason. People go in and out of our lifes frecuently....possibly to teach us very important lessons.
It takes time to get over a heart-break especially if you have loved that person dearly. Cry...cry all that you need to. Let it all out. Let your feelings and your tears flow...after a while you will feel better.
After a few more years and a few more heartbreaks, you will become indifferent to it.
Because being betrayed, or losing love, really, really hurts....and then you get depressed. The only way to stop crying is to start thinking about other guys...seriously. I know that sounds impossible right now...but it really does work. A new guy will help to take your mind off the heartache....and help you move forward.
got money go buy yourself something you wanted. Then get together with your friends... surround yourself with good people till you heal.
