Re: Is she stalkerish or desperate?
You can't let it go because there are some issues, be it physical, hormonal or emotional that won't let you. If you could completely put her out of your life, then I would say that it wouldn't be that hard to get her out of your mind, but this stuff is stressing you out man.
It seems that she is a part of your social circle, and for whatever reason you will have to see her from time to time, therefore it is going to KEEP bugging you and KEEP being an issue until you deal with it and get on the same page with each other.
The reason it keeps bugging you is because you are a human being.
