Hello all,
Update for those who are interested. I gave WS a variation of the sandwich speech, and that initially worked well. She went NC, blocked his number, and deleted it as a contact. She permanently deleted all archived messages to prevent her from recovering his information while drunk. She removed him from social media contacts. All of this was immediate. The OM tried to contact me to ask when someone could come pick up her stuff at his place, but I told him to donate it or throw it out.
WS confessed that everything I had suspected was, in fact, 100% true. She talked about being scared she had become so caught up in an infatuation that she nearly threw her whole life away. She was upset with herself for how much she had hurt me. So far so good.
Then we went out to dinner, and much of the conversation was about her trashing OM. This felt good and cathartic at first, but it was also a sign that she was getting fed up with him anyway. She mentioned that the last thing OM had sent her was a cryptic text about needing to "work on himself", so it seems he was breaking up with her. I can imagine that had I confronted WS a couple weeks ago, her turnaround might not have been so fast.
WS talked a lot about how she felt that she and I had trauma-bonded at the beginning of our relationship. We had both left abusive prior relationships. Our respective bio kids needed lots of help when they were young, mine in particular. My ex-wife re-engaged in a custody battle that took years to resolve at the beginning of my new marriage. My WS and I never had a honeymoon because our kids were little and I was drained of funds from legal matters. My WS concluded that we hadn't really dated properly back then.
(Note that in my mind this is actually false. I hired sitters, and we went places. What I did learn was that it was hard to do much more than spontaneous dinner/movie dates because her capacity for planned events was unpredictable. I remember one time I had planned an evening around a concert by her favorite band, Social Distortion, but we never went because she was hungover on that day. It wasn't a surprise; she knew about it for weeks. I concluded back that I'd have to improvise.)
WS stated that she didn't really know how to have fun with me. This is interesting because she didn't do anything special with OM that she could not do with me. The only thing I can't do is sing songs I wrote for her at open mic night, which was the hook that got her in bed with OM the first time. I think what she really means is that she doesn't know how to have fun with someone who isn't drinking and isn't able to be out until 1 AM on a Tuesday because he has work the next morning.
She said she wants to fall in love with me again. This really kind of ground my gears. There is an undercurrent of shifting the blame on me. I lived through those same things. I don't need to learn to fall in love with her. I never stopped loving her. I never stopped taking care of all of her needs. I stayed faithful. I'm not saying I'm perfect, that I don't need to address my role in her unhappiness, or that I don't need to consider how our relationship might change as we approach empty-nest status. However, the initial vibe really seemed to be that the work of repair is mostly upon me. OM is gone now, so who's gonna fill this hole of boredom now?
So the hard work begins. We're not out of the woods. We're not even halfway into them. But I guess we've started the journey.
