My partner cheated, and I reacted by closing down. I thought I had forgiven initially, but what it turned into was "OK I will love you less and you can't hurt me" and finally "I now don't give a shit about you". Ultimately I told him I did not feel the same, and he could no longer hurt me.
Basically under the tutelage of COSA I reasoned that I could not control who he slept with and when, so I basically may as well not worry about it. Assume it happened, and care less about it.
And this is what he heard..
"I want an open relationship" Or more particularly..."You can sleep with who you like."
Now this most certainly is not meeting my needs. You get to sleep with who you like, and I get the manage the property?
What did I just give away? The last vestige of belief in a loving, respectful, trusting cohabitation between a man and a woman. He may think he can sleep around and still "love" me. No matter how I reason it, I can't see that as love. If I was doing that, I would not be loving my partner.
I understand a lot of men can still love their partners and sleep with others.
However I think the point I am trying to make is that, regardless of what he is doing - he may be doing nothing at all now. There has been a perceptible shift in my thinking that is really the point of no return. Out of self preservation, I no longer love him. And that the relationship has become asexual is inconsequential. I doubt our relationship could now be fixed even with a good dose of healthy marital relations.
