Edz, you seem to be in control of your thoughts and you seem to be very much in control of "the thing". If it is a deal braker for you then I'm sorry as it's hard to reach that point because no matter what you still love her. I think 99.9% of people coe to this site because we want to save the M and are prepared to accept alot of sh1t from their WAS to reslove the M. My own sitch has got to your point but I still find myself looking for hope and its only this week that I have found that I am not looking forward to seeing W or talking to her. I suppose with time, you start to realise that there is no quick fix to anyones Sitch and life does go on.
I hope that "the thing" is not what it seems and even if it is, take it out of the box, etc.
