Little GO, i think him wanted to move in suggests that a part of him even if it is a tiny part wants to be near you too because regardless of whats best for the boys if he was 100% done with you he wouldnt want to be in the same room with you for 5 minutes let alone wanting to move back in - I should know as my husband is not wanting to see me at all or even be in the same room just so not to mess up his R with the OW, so this is positive and as DB says baby steps and staying positive. Affairs in many cases end and they are usually built on fantsasy and comes a time when the excitment wears out and then depression sets in and i think your husband is in this stage but because of his ego, men's pride whatever he is not willing to admit it and using the boys as an excuse to see if his feeling for you could return. he probably doesnt want to committ straight away for the fear of leading you on and hurting you if his feelings dont come back...but the chances that his feelings return whilst he is at the house with you are much higher than if he is out and free to spend as much time as the OW as he wants. If i was in your place i would agree to his proposal, let him come in, live in the other room but and i have to put this BUT in capital letter, go about your own business, do exactly as you were doing when you started the 180, take care of yourself, go out, be happy and date others and dont pay much attention to him! let him get on with his life and you live as friends but try to make him see the amazing happy person he is about to let go of. believe me this is an amazing chance if you want to save your M but you need to be strong and unemotional! when i started doing 180 it was very difficult but a friend told me something i wasnt seeing and that was the fact that since our seperation i had been very emotional, an emotional wreck if i may say and no man would want to be with someone like that, even women wouldnt want to be with men who are emotional wrecks! be very strong if you want to save this and try to put your emotions and feelings aside. if he moves in and in time nothing happens and you feel u have had enough then you are free to ask him to leave but at least at that point you would say at least i tried and will never wonder what if. the last advice i want to give you which my DB coach told me is IGNORE the OW!!! dont talk about her or mention, basically pretend that she doesnt exist and dont let her come between you even when she isnt around! you are not in a relationship with him right now so doesnt matter who else is there, all you want to do now is make him see you in favorable light, this will benefit both of you! dont ask him for R or beg him for anything. act like an adult and mature and if he wants to move in he has his reasons he is not telling you, i would advice you to take this chance but cotinue getting on with your life. in the end the decision is yours and it depends on how much you can take and endure but this is what i would do.
