I'll Break it down, noob.
1st try to talk to her if no response go to step 2.
Step 2 play her same game, she wants to be In control. So play her game, don't text, call, facebook, instagram or any of that BS with her.
3 hang out with friends, go drink a beer have fun.
4th don't weep your sorrows away.
5 after a few days she will talk to you.
6 if still not have heard anything you have gone 6 days already.
7 you send a message, say you need your things back. You can just put here or there or visa versa if you have her stuff.
8 days is far long enough go to the bar have a few drinks start communicating with some females. This is most important don't go for the baddest bitch in the bar you won't get or if you can you will catching something. Find the girl no one is really talking of she isn't that hot drink a few more(don't tell your friend loose lips sink ships remember) buy her some random drinks early in the night, chit chat, drink some more. Then take her to your or her place handle the business and you'll feel much better. Get dressed and roll out. If you get rejected from the baddest bitch u will feel more like shit and then say god must be telling me not to do this etc etc. Its now been 9 days repeat day 8 a few more times and your now over her and ready for new things it works
