I would love to help you @Tisky, but I honestly can't think of any advice that hasn't already been given to you. Plus, I'm incapable of looking it from your perspective because my mind doesn't work that way. Whenever I had heartache, like the time my ex left me for one of my best friends 4 months after we bought a house together, I reacted completely different. Even though I lived together for 5 years with her, my way of processing things was to erase her existence. I changed my email, phone number and what not, completely ignored her and really send everything I had of her, including the most expensive gifts, back. It drove her crazy and made her try to stalk me, but I didn't care. Even years later, she send me a letter, personally delivered through a mutual friend, which I immediately threw away without reading. Something I never regretted.
It's not that I didn't want to talk to her, or that I didn't miss her or wished she would come back. No, it's because she was a lying sneaky slut that stabbed me in the back and I deserve better than that. It's because I love myself more and most of all, it's because I'm stone-cold unforgiving vindictive motherfucker that doesn't take shit from nobody. You can bet your ass I gorilla fucked every girl I could and partied like my life depended on it. And you know what? That pain slowly goes away. You'll think less and less about her and eventually it's just another burned bridge, with a distant memory of the smell of smoke and the assumption that once your eyes watered.
