Divorce after 7 years

Hello,
I am a 58 year old male.
I was married for 26 years and separated 7 years ago due to differences.
My wife has lived in our 4 bed marital home for 7 years, the mortgage is on myself, she doesn't work and I have paid for the mortgage and bills while living in a one bed flat. I am also registered disabled.
The reasons behind not divorcing sooner and supporting her are private and hindsight is a wonderful thing however I'm pushing the button now ..
I started proceedings with a solicitor in January with a good offer re house sale and settlement, solicitor has all financial info, groundwork done. She is dragging it out because I guess she can stay there for free and disputing the offer on the grounds of she thinks I have more money etc.... I don't want to stop paying the mortgage as it will black list me.
So my solicitor has put in a final offer or we go to court.
I am absolutely drained - my solicitor advised that if it goes to court I'd have to pay upto £30k fees - she'd pay nothing as she hasn't applied for it. Will the court look at her in favour even thought I work and supported her the last 7 years. Our kids are older and living elsewhere.

So I feel that this is a losing streak - I'll still pay for her to stay there, she doesn't accept letters so it drags on and on - court will take a long time and costly.

Is there any hope for me or advice to get this settled as the strain on my mental health is so great and I'm worried about the costs I'll have to pay as she's not moving things along or accepting offers.

Thanks

You don’t mention incomes or other assets other than the house.

Your ex doesn’t need a four bedroom house so ultimately it will probably be sold.

What is she doing about finding work?

Mortgage wise you talk about being blacklisted but have you spoken to your lender.
