I spent the first 2 weeks after he moved out using every ounce of willpower I had not to call him and beg him to forgive me for such a terrible mistake. It didn't help that I knew he'd do so in a heartbeat. I had the phone in my hand and the number half dialed on more occasions than I can count. I spent the next couple months constructing scenarios in my mind about how we might end up back together at some point, when I was more ready for it. Now, 10 months later, I'm finally at the point where I know beyond any doubt that it was the right choice for me. There are aspects of our relationship that I still miss like crazy and I believe I always will - but I'm glad I can have those pleasant memories, rather than having them poisoned by the negativity that would have grown out of control if we stayed together. I have a ton of regrets, but I know I'm better off now than I would have been. Will we get back together someday? Unlikely. It's not entirely impossible, but I don't think it will happen. Edit: If you do decide to leave, know that the decision is final. Don't do it with plans of going back to him someday, because that is unfair to him. It keeps him dangling, hoping, waiting for you, while you go do your thing and have fun - and that right there is some serious bullshit. I know it will hurt you more, but have enough respect for him to allow him to move on with his life if that's what he wants to do.
