What a shame, Eve - I remember you and wish that you had moved on with strength and without him. So sad to read about you feeling this way. I fear that he will always treat you badly, because he can.
Shaz - and all of you on this thread facing similar situations, the moment you start taking back control - and stop passing it over to the people who have hurt you, you will feel better.
While I understand the desire to make leaving you, his decision - don't wait for too long. All the while these men think that they have a choice, they will dither. Usually it is when they think that they have lost everything, they find that they want you. Also, because so many of you are completely unsighted on what the OW wants, I cannot imagine that you want to wait for her to decide your futures.
If I were you, I would be making ultimatums and if their choice is to leave, showing in my every action that there is no way back and that they must live with that choice - forever. Hopefully you will in time mean it too, but for now it is important that your Hs believe you - and realise that they have lost you permanently.
I have never known anyone made happy while they were in limbo waiting for others to control events. I have known numerous people who were happy after they started calling the shots, some with Hs who returned and others who went forward in life alone, with their DCs.
