Several things I have taken note of in this thread -
1. Your an idiot.
2. You have resorted to make a fake facebook account in order to spy on your girl.
2.1 - Why would your girl add a complete stranger she has never met to her facebook account? If she did add you, shes as big a fool.
3. You are spying on this girl to see what interaction she is having with her ex. What, you think she is gonna post shit like "thanks for that wonderful sex last, just what I needed" openly for all to see?
4. I must have missed your other posts, but judging from replies, they were equally as pointless.
The trend Im noticing is "You are spying!". Isnt that enough for you to throw in the towel and move on.
If she knows its you then she sure as hell wont forgive you for it, there is no reason in the world to excuse it. If shes not interested in you - move the fuck on.
Cut the ties, get your stuff and go!
Why is common sense the last thing to cross a persons mind?!
You know what, in fact, stay. Be a damned mug, be played like an idiot. It keeps the board alive with threads like this for people to have a laugh at others expense.
