You are in total control of seeing her facebook page. Stop. I had to stop myself too, and I've only been there about 6 times in the last five months. It's not doing you any good and you know this. The fact that she hasn't blocked you and is doing this to get a rise out of you shows she enjoys this attention and enjoys torturing you and does not respect you. You are subjecting yourself to this torture...why? Do you think you deserve it? No? Then why do you do it?
Stop saying you need her too. You don't.
You are just running on a hamster wheel in a cycle of self loathing. Haven't you had enough yet? Do you know that if you stop, the shittiness you are feeling WILL go away? Isn't that what this is about? To take away the pain you are in?
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
