I agree the telling is done--he wants 6 more months of limbo. It's up to you now whether you'll accept 6 more months of limbo, or you're ready to move on with your life. You have as much time as you need to decide. Remember that D or moving on with your life doesn't prevent him from later realizing his mistake and attempting to woo you back, although he may have competition or to do more work by then!
