Honey I really feel for you on this one. I can't even imagine what you could be going through after all that time. But the best is to move on without thinking you might reconnect in the future. If you don't, your always going to be waiting for her and you can't do that to yourself.
True you don't have to date anyone or do anything like that. But you need time to get over all this. Focus on yourself and do things for you that will make you feel good. Hang out with some friends or take a vacation.. also make some goals for yourself to accomplish one by one to gradually get back into being single. I know it's going to be hard but you have to start somewhere and I wish you all the luck in this.
If you can't handle the thorns, don't crave the rose!!
