Steps
Monday: Cry it out, release your feelings!! This is the best thing to do to vent out whatever you feel and just have some alone time.
Tuesday: Talk to a friend or someone trusted about what you thought about your ex, but think more about why you broke up.
Wednesday: Go out with your friend for just a day out of relaxing and enjoyment. Make sure you don't go somewhere that will bring memories of your ex. Wednesday (just a representation of what would be the 3rd day after your relationship, it could be Sunday, or Thursday, or whatever.) is the day to forget.
Thursday: Get rid of any possessions your ex gave you. You can keep them if you think they are beneficiary or they bring good memories, but only look at it as a token of friendship, not of your relationship. If they bring bad memories, then throw it out or dispose of it in any way you desire. Don't hang things from your ex all over your room. It shows that you are still obssessed and really into your ex.
Friday: Think about the past week and how you have done without your ex. If it was fun, and you weren't thinking about your ex 24/7, this is a good sign that you are ready to move on and release those feelings for your ex. If you have been sad, or constantly think about your ex, you are not ready, and maybe you are still in love with him/her. Make sure you know the difference between love and missing your ex's presence. Never rush yourself, the healing process takes a long time, and it may take several weeks, and if so, just stretch out this process, and spend a few more days venting out feelings, and then go onto the "tuesday" process, etc.
Tips
Act in a respectable manner.
Never talk about your ex boy/girlfriend because that can cause some problems between you and your date.
No matter how badly you want to keep all your facebook/myspace etc. messages, DELETE DELETE DELETE!!! Hand written letters and emails can be printed and stowed awayed to be looked at later but until you can handle it, pretend she doesnt exist.
Keep a girlfriend box, later, when you are over her you will appreciate having those memories.
delete her phone number. i know its hard but you dont want the drunken phone calls and texting to start. when you are over her you may see her on a night out to a club and then u can either ask for it again as friends or you realise you dont need it.
