Divorce in Oregon - "equitable distribution" with a freeloader

Hi. I've lived with my spouse for 8 years, became registered domestic partners in the first 6 months. Bought a house (down payment was proceeds from sale of my previous home, owned exclusively before I met my wife) 6.5 years ago. Married 4+ years ago. Spouse has worked a total of 6 months since we moved in. I have worked uninterrupted this entire time. House in solely in my name. I put my spouse through college... twice. Once earning a certificate (then she worked for 6 months), then for a 2-year degree, after which she has never even applied for a job.

We've tried marriage counseling, but it blew up spectacularly. Without trying to be too biased, I can say I wanted us to approach it collaboratively, but she treated it as an adversarial situation. She wouldn't respect the ground rules set out by the therapist (no talking over each other, that sort of thing). She blames me for everything. Makes excuses for everything. Gaslights me -- tells me I remember everything incorrectly. Sleeps until 2:00 pm every day. Spends her time scrolling social media and watching reality TV.

She does NOT do housework. We don't have kids. She doesn't make any sort of "equitable" contribution around the house to offset the fact that only one of us works.

She has a drinking problem (addiction problem might be more accurate). Shell drink a bottle of wine a night until I can't take it anymore (b/c when she drinks, she's not so fun to be around). Then she'll stop or slow down for a week or two, then the cycle ramps up again.

OK... not trying to heap on, but trying to paint the scenario.

I will also say that... sigh... we have our moments. But, honestly, since the first year of dating, it's just gone downhill. So, so far downhill. We don't have fun anymore. I don't enjoy her company much. She might feel the same. I think she won't leave because I am her meal ticket -- sorry for how misogynistic that sounds. It could be either partner. This situation isn't a result of gender. Yeah... OK... sometimes I wonder if things could be salvaged, but there are deeper layers (her refusal to be accountable, her lack of ambition/initiative, and on and on).

I am meeting with a lawyer soon, so I will be getting professional advice. Wondering a bit how screwed I might be with a divorce. (Close friends remind me I'm paying for my freedom.) Wondering if we were to go to a judge with an uncontested divorce if the judge would tweak things in her favor or meddle with the terms -- and whether there is a way to paint the picture of how one-sided things have been, which would justify an "equitable" decision that reflected the contributions of the one earning partner.

Sigh. Sorry if I'm spiraling. I guess... just asking if anyone has similar experience or if anyone wants to chime in -- keep it constructive, please.
