Dear hurts:
Yes, love yourself, choose yourself over him. Be on your side, take care of yourself. You should be your focus, not him. And as much and as often as your thoughts will continue to be about him (because this is a habit by now), re-focus your thoughts, move them again and again… and yet again back to yourself. Like any persistent habit, this mental habit of yours needs to be broken and your interest, I hope, will be centered around what you are about: what hurts you, what scares you, what you need, etc.
Please post again, anytime, and let the rest of your thread be about… you!
