Why can't I let this go? Why is it so important for me to be "right" and him to be "wrong"? Do others do this self defeating stuff and is it another iteration of bargaining? The false hope that somehow he might " see the light"?
Hi
I have been total NC for nearly a year after I ended a 13 yr r/s about 18 months ago. Looking back, I was the same as you for quite a while until I went total NC. It wasn't so much having to be 'right' and 'wrong' but I very much wanted him to take responsibility for what he had done. However, my way of communicating (because I was really so angry and hurt) most probably didn't assist in him being able to do that - in whatever way he could. . .emotions were too high.
But, it was VERY much wishful thinking that he would see the light.
Strange thing is, in the only way he knew how, I think he was trying to open up but it was almost impossible. . .and there were issues (cheating, lying) that he never would have acknowledged. . .his 'other side' had been exposed and it was something I knew in the end I couldn't live with. . .and something he wasn't prepared to try and change. It is far easier to rinse and repeat
In the end, to be truthful to yourself, you have to ask 'can I live with him as he is'. . .because your pleas of how it makes you feel in the hope for him to change is unlikely to happen. The thing is, as his words don't match his actions - he loves you, wants to marry you but hurts you - neither do yours. He is making you feel humiliated, his values towards relationships don't match yours but you are still taking it?
It is HARD to detach from someone you love but if you want to do it 'kindly' then I agree with others - stop trying to rationalise with him - it's either you let him know you are no longer keeping in touch (and you have to do it) or you go low contact and get some advice/read the lessons on how to communicate.
Good Luck
