No HELOC. I don’t know if he has opened up any credit card accounts besides the 2 we have in both of our names.
We have 2 car payments. His car, and the 3rd car for D. Mine is paid for. Title might be in his name though!
We have about $18K in PP loans for older D’s tuition. As I said upthread, paying that down quickly. Not much in savings as we are throwing the money at that loan to make it go away.
Younger D has a full ride. Her biggest cost for college is health insurance, plus the tax on her stipend, plus her having a car.
Mortgage. No other debt. Credit cards are for convenience (and points) and gets paid off every month.
Jobs are “okay”. No benefits. He is a very minor partner at the business. No pensions. Not much in IRA (under $80K)
The lawyer I consulted with last year specializes in divorce, has been in practice for many years, and I know (casually) 2 people who have used her and highly recommend her. I was pleased with our first meeting. She recommended I have an open conversation with him, and here we are, six months later and I have not. Bawk.
I will go over the finances, again, this week. Any excuse to make a spreadsheet, people! 
I am guessing (only a guess!) that finances will come up, shortly, when he gets back from vacation. I anticipate him having a sudden interest in where his paychecks are going, and wanting more control over that. Several “little things” he has dropped in conversation the last few weeks have raised my antennae.
I can only assume he has been giving some thought as to what he wants in the future too. It would be easier, in a way, if he forces the issue instead of me.
Meanwhile, I wait for the plumber to come fix the leaky supply line from the toilet. Yay you beautiful old 1924 house! Renting an apartment is sounding not so bad about now…
