Is it normal that i feel like stalking my ex new girlfriend on face book?

[E-ma]

Define "normal"
1. usual: conforming to the usual standard, type, or custom
2. healthy: physically, mentally, and emotionally healthy
3. occurring naturally: maintained or occurring in a natural state

Yes, by definition #1.
Definitely not, by definition #2.

Sure, curiosity will make you look where information is available.
But after a year, you've gotta' know that this is not emotionally healthy behavior. It keeps you from moving forward in your life. You may be going through the motions, but there's still a part of you stuck in the past. This is how people behave now-a-days b/c social sites like FaceBook exist. I prefer the old ways when rejection was made, & people moved away from that rejection and towards the acceptance by people who DID appreciate their value.
