Now is the time to re invent yourself and your life. This is for yourself and no one else.
1) Please abide by no contact - ignorance is bliss (not sure if this is possible in your circumstances)
2) Go out and have a gr8 time with your friends (party)
3) Date other guys if possible and flirt big time (nothing serious)
4) Ever wanted to do something in your life like travel, a hobby or see a band you've always wanted to see? - Now is the time!
5) Its gonna hurt for a while - but trust me your not alone, most people on this planet have gone through the pain your going through right now and whatever didn't kill them made them stronger and wiser.
6) Treat this as a life experience and be glad it happened to you now and not when you had children or were more commited
7) Never be Dependant on anyone else apart from yourself as you really are the only person who can make your life what it is
8) Your ex is not dead and hes obviously having a great time without you - the best revenge is to be happy yourself as he obviously is having an awesome time!!
9) You may be friends again or you may get back together but at the moment you have to let go and move on with your life, you have only one life so don't wait your entire life for something.
10) Here is a quote to make you think: The greatest effort is not concerned with results :]
