Seriously dude I would overlook you because as you are right now you are just one big ball of red flags. You really need to get your shit together and take some responsibility for yourself. You have no-one but yourself to blame here for why things ended with your Ex, she was right to lay down some boundaries. I've given you some practical and positive advice but there's no helping you when you're intent on whinging and shitting on yourself at every opportunity possible.
