I have some very good news - and it is coming with a really powerful bit of learning that I want to share, in case it's helpful to others.
The good news first (because we all need a little lately): I AM GOING TO GET TO KEEP THE HOUSE AFTER ALL!!!!!!
In a totally unexpected turn of events, we decided that I will keep the house in exchange for him not having to pay any spousal support. It more or less works out in terms of financial value, and not only does it give me the house but it means I don't have to rely on him financially ever again. I just refinance for the current mortgage and we call it good. Double yay!
I thought I was going to lose the house, which was my forever home, so this feels really, really good. Or does it?
So here is where I had my bit of learning (so much gets clearer when you are no longer in the relationship, right?). In the history of our marriage, I enabled his childish emotions. As my therapist puts it, "I deferred to his distress." If ever there were a situation where he felt distressed, the family system was that he would somehow passively put out a statement that sort of implied that I should make a choice, and make it the choice that would remove his distress. For example, if we were trying to decide on making a big purchase and we came down to two choices. I preferred one, he preferred the other. He demonstrated his distress about not getting his choice, and put it out in a way that I knew it would be easier all around if I just overtly stated that I preferred his choice - instead of mine. I was the grown-up, but we never even got to having a fight about it, because I preemptively deferred to his distress and accepted his choice. Once or twice I stood up for myself, and we agreed on my choice, but then he became grouchy or sullen or angry or whatever little children do when they don't get their way. Instead of helping him learn to deal with his emotions, I enabled by agreeing to reverse and make it his choice. I could not tolerate his distress.
So, through our (excellent) mediator, we came to this decision about the house - with that third party helping us through and there to witness the agreement. He is very, very sad now (I was very, very sad before). He is distressed. I could even tell, during the mediation process, that he was fully expecting me to not go there and to not conclude this deal. But I was ready (thanks, therapy) and I DID NOT DEFER TO HIS DISTRESS!!!
So now it's a day later and he has asked that I give him "some space for his grief" before continuing with the plans for him to move out and me to move back in. He is distressed. And I can feel how much I am uncomfortable with it. It's really fascinating to observe this in myself. This is me unlearning my enabling behaviors, and being willing to tolerate his distress. And why? Because I no longer need to protect the relationship and avoid conflict with him.
For those of you who are subject to enabling behaviors, this was a good lesson: recognize that it's really, really hard to tolerate their distress and really easy to tolerate your own in comparison. That is what you are accustomed to and what your family dynamic supported. You no longer have to do that. You can give them the gift of allowing them to manage their own distress and leaving them alone to do it.
Now I'm going back to being BEYOND HAPPY that I am getting the house!!!!
