You don't owe her anything, she's your ex now, and unless you have a kid together there is no reason to ever talk to her again. The drinking is pure self pity, let it go, cry, scream. whatever but stop trying to drown your sorrow as sorrow floats. Get help if you need to, better to just get a different outlet for your hurt, exercise comes to mind, join a gym, get some running shoes, join a Karate dojo and become a better you.
