GC - yep well done you are one step closer to the loonybin, carry on like that you will be wearing this seasons backless white gown before the end of the month
I caught my ex-dh in a lip lock on the sofa with my friend, they thought I was asleep upstairs - she had been drinking so I let her stay in the spare room rather than drive which I thought was very good of me. Ex Dh and I argued all night about what had happened. At one point he even said I had imagined it and said and I quote 'You should go upstairs and apologise to the poor girl because she is wondering what she has done to upset you!"
Believe it or not I can actually laugh about this now, he and she are out of my life their 'fling' or whatever it was (I shall never know) cost her her marriage as well. Last I heard he had got custody of the children and she was out on her ear.
He lied and lied then lied again about everything, same as your man - you are wasting very valuable time and energy on getting mad and wanting to get even - to be even with him you will make yourself his equal.
That is where you are heading - this will only get uglier and messier. Call a halt now - HE HAS EVERYTHING TO GAIN FROM YOUR LOSS OF CONTROL
Calm down and start thinking - you obviously care deeply about this man or you would just shrug and let him get on with whatever he is doing.
He hasn't reduced you to anything, GC you are doing that all by yourself.
Stop torturing yourself - get to the esate agents and start looking at moving!
