For the most part my experience sounds similar to --sd-7......When I quit almost 6 years ago life became hell for over 2 years....my 'christian' JW wife screamed "I hate you" in tantrums that would last from a few minutes to a few days for an almost 2 1/2 year period. I did my best not to retaliate in kind, but I gave in a few times. I think at one point I had a bit of a nervous breakdown.....I was sleeping alone; she had moved into another room......and woke up jerking around violently in my bed; I could not control my body. Quite scary....when I was finally able to stand I went to the room where she was sleeping and started shaking her hard. Her head was wagging back and forth and I realized I could hurt (maybe worse) her without much more effort. so I collected myself and went outside. At 1 oclock A.M. pacing the driveway for nearly 2 hours I had to tell her to get out of my face, stay away .... I didn't want to hurt her. I wondered how many neighbors picked up on the commotion. Life has never been the same. I have gone thru several stages of feelings toward her.....shock, dislike, vehemnet dislike, hatred, and now apathy. I don't love her anymore. We haven't been intimate or had sex for nearly a year I'm guessing. I care for her welfare, but not much beyond that....sort of like caring for a pet......not wishing any harm on it but not crazy about it either. I have wondered if she is having an affair, but if she is: good for her. I am contemplating the same for me. And thats the hard part of apathy....if there is an emotion, there is something to work with. Apathy offers nothing. But I have too much invested in this......45+ years, 2 adult kids, 5 g-kids, 3 g-g-kids, a paid-off house, no bills, 4 streams of income, cars paid for, etc.,etc........too much to walk away from or to be willing to give a huge chunk away to have .....what??...peace? Maybe, I don't know. So, I too live with an elephant in the room.
I have no advice for you. You have to do whats in your heart, but be prepared for the long haul. It usually isn't easy.
