Maybe he just doesnt want to make it harder for you? You have never hidden your disapointement just not to get someone upset/hurt or emotionally blackmail them to do what YOU want?
Why are you here? Is your husband reading and you are sending messages to him?
I dont understand. He is telling you he accepts your decision and you dont like that either?
I know the kind of bitterness you are feeling. I've been there, done that. And yes, for me too, him having sex with OW was/is the last thing on mind. The lying and the deceit were what hurt most. Some people can do it and get over infidelity. Some cant. You decided you will not. Perfectly fine with me. Still, I get the impression you are secretly hoping for some kind of another recation from him to...I dont know, change your mind, prove how "right" and justified you are?
One thing I can tell you from my experience: dont make any rush decisions while you are still in this mindset. Chances are, you will later on regret that you didnt give it another try granted you say you love him.
Is your C pro-marriage? Does he/she believe infidelity is a dealbreaker? Double check your motives, influences, environment, heart and mind. K
