I hate where you are and I know all to well what you're feeling. If you want to cry, then cry. It makes no difference what an *** this guy is.. you obviously love him more than yourself to want him back. I'm afraid it doesn't matter how many tell you the truth about yourself, if you don't believe what you hear due to your thought process, you're only treating a symptom of the pain. There's no set time to get over someone you love. You will do it in your own time. The more honest, truly honest you are with yourself the better. There's something called "the Work" I learned about it in the hospital after I ate 30 zanex followed by cough meds so i could "sleep" without my husband after he left me
Learn to examine your actual thoughts with the logical side of your brain by writing them down, followed by questions that will examine the truth of those thoughts. Read them outloud to your self when you're finished with that single thought.
Our thoughts are learned from life experiences and feelings. If you relearn your brain to think with the logical instead of the learned feeling side.... You will find it much easier to cope with this loss. .

this is gonna come off corny or pointless but try it out loud

example: "He moved on a long time ago, but I can't"

is this true? but I can't"
logically speaking..did time stop for you? do you wakeup everyday?
are you living?
answer this outloud so the logic side of your brain hears you
No it's not true. you are moving on... everyday you're a breath closer to being well.

We can all tell you what you already know... You deserve better than him. But until you FEEL it... Do what it takes to heal and know you're not alone.
