oK, looking in from the outside- guess what? YOU ARE PIECING. He came back. He says he wants to end it with her, but sounds like he is not doing it fast enough for you, and I can't blame you, I am sure you wanted it to be over the minute he walked back in the door. You have told him for a second time now that maybe you should have moved on. And he still contends that he wants to stay, and sees you two together at the end of the tunnel. Ask yourself, is this what you wanted, for him to come back? If it is, you BOTH have work to do. Would it make you feel better if you gave him a deadline? Ususally ultimatums an deadlines don't work for a R, but if its really gonna make you insane that he is doing this at a snails pace, then you are really setting a deadline for yourself, right? Do you feel like you want to tell H " I know you are trying to end this with OW, and I am so happy that you want to be with me, i still love youi too! I'm impatient cause I want our happy life to begin right away. I am having a hard time dealing with this, and some issues we can't resolve till I know she is out of your life. I am giving myself till xx/xx/xx to see if I can work through it , and if I can't I will need to decide if aI want to continue our relationship"
Sounds pretty ultimatum-ish, huh? But the bottom line is do YOU wnat to stay. I know this come back of his was pretty quick ,and he may very well be seeing how long he can have his cake and eat it too. Would it help him if you went with him to tell her its over? Some people here have done that. But this really should come from him if he is at all serious about leaving her. I don't know your H , so I can't sya what would be pressuring to him. But i do sense that you want this over , you want it over NOW, and if you can't get it yesterday, you want out. So i feel this is really a decision about you at this point. What do YOU want to do.
