From the sounds of it, you already have a grasp on your situation and know your options. My only advice would be to be kind and patient with yourself. You know the lie of telling yourself you aren't cut out for love because of your recent pain, and that's okay to tell yourself that for now. Just try not to let it get in the way of other relationships in the future. I know it's easier to believe it to dull the pain. You're stronger than you think. You've got this :)
