Hi Allie,
I'm sorry you have so much on your plate....... here is my 2 cents

It's so easy for the LBS to forget that their MLC'er is a broken person. Broken. Not fully functional, not partially functional. Broken. No function.
We want to see what we loved, and wonder "where are they?", "will they come back?", "I want one more glimpse of them - the person I loved".
In your case - he passed away before you could even see if he could put himself back together. That is tragic, heck, MLC itself is tragic.
The truth is, no matter if he would have been able to reconstitute himself or not, the exact man you knew was gone the moment he broke.
That is one of the bitter things we discover as LBS: That person, that personality, that unique fingerprint we knew is finished. It will never be THAT person ever again. They have changed from damage - and we change from that same damage.
What I would say is: You loved that man for 24 years........ you were his, and he was yours. It was completely and totally real. No question.
The break which is MLC produces something else, someone else.
When you look at all he did towards the end - that isn't the man you knew, is it? No it isn't. I'm sure the earlier version would be aghast if he could have looked and seen the later version.
So you see, you had the best, you had his best, and he had yours....... that was your time, and that was love.
You aren't saying goodbye to the broken human, you're saying goodbye to the husband you remember, and loved.
That's why it's so hard. That's why it's so difficult to let go.
Here is your comfort: You remember HIM. You are the only one who does and will, in the way you knew him.
Like an album of pictures, so is your life. You get to take out the photos of him at the end, because those were the broken human.
Look at the good years, the good times, and all you were blessed with....... and smile.
After a time, you will close that book and put it on the coffee table. A while later it'll be on the bookshelf.
New pictures will be made and placed in that book of your life, but always you will be the keeper of memories. There is no reason to honor the broken human, but there's every reason to remember the person from before.

Take care sweet AllieKat,
