Sorry so much has gone on - this is all so familar to me and i know exactly how you feel. Your whole world is shattered.
Are you scared that he will leave or that he will go to her? You want to win at whatever cost (i have been there so i should know). Your head is telling you that you will be better without him but your whole body is saying something else.
I think he really wants you to throw him out and it is up to you whether you now want to give him what he and she wants.
You can do this we are all here for you and if you want to cat me feel free to.
You know you cannot make him stay and deep down you do not want him on those terms anyway, but you must also realise that you can never go back to what you had you will have to now take back some of the control.
The ow has the advantage over you in that she knows he is lying (and beleive me he is having an affair - the same lines my h said to me). She can also afford to wait for him and be there to pander to his every need at the moment. This is not the real world and the second he realises this is when it will stop and end.
Would you consider contacting the ow to discuss it with her? (I did this but was fed a load of bull).
I think the advantage you have is that he will never be able to cut the ties to you and as long as you absolutely show him it is you he really wants and needs he may change his mind.
Your h is 'addicted' to her at the moment and he will find it so very difficult to have no contact but that really is the only way if things are to go forward for you two. For whatever reason he is not ready to give her up and he thinks that she may give him what he needs.
Oh i feel so very sorry and sad and angry for you there really is nothing much you can do except let it take its course.
You are a strong woman and you will cope and come out of this really shitty time with your dignity and courage in tact.
It is not easy but you are a fantstic person who is willing to forgive your h this - you are not a fool or a mug. And even if you are i would rather be a fool everyday of my life than the type of person your h and she is being at the moment.
Be stong and keep posting.
