Short answer. No.
Some people (narcissist?) are so selfish they will only look after whatever feels good (or necessary for survival) right up to death.
I posted to pretty much same question some a few days ago in another thread.
My perspective hasn't changed in decades.
I say - and I think a lot applies to your situation.
My opinion - you should change your expectations and efforts towards trying to convince your spouse to be a part of your son and daughters life.
Why:
I am thinking at the age of your spouse - he is unlikely to ever improve enough to be a positive experience as a "dad."
Some men (some women too) - are self centered and looking mostly to enjoy their existence as best they can given the place in the path of life in which they currently find themselves.
I am not implying this is necessarily your husband but I see, from your post, that he is conflicted with what he wants.
He has a home (had) with wife and two kids.
Finds another female to cavort with and gets an apartment together.
Where is guilt a moral person would have taking money from family for such action? Where is guilt for leaving two children wondering WTF is wrong with their life that their dad has essentially removed himslef from their daily life?
My answer - he is only concerned about HIS pleasures (as he sees them) and either doesn't care or just doesn't give a thought to how his actions are affecting his kids and you.
- one of my quips: quit relieving yourself over the windward side of the boat.
To continue your current path of trying to push his involvement in your kids life is going to cause you anger and frustration. It is a pointless effort and, I would guess, 100% not going to happen without a LOT of change in your husband.
I offer this perspective based on my life. I grew up without a "Dad" - ya - I had a father - a sperm donor.
He was never a dad - only ONCE in all the years he was alive (and rarely around) did he EVER take me , as a son, to anything as a dad/parent and son that would be quantified as a activity that would foster some kind of bonding.
He took me fishing - with another "dad" and his son. They drove us to a lake and said "Here is your fishing rod - have fun!" and then sat in the car (50s Ford) and polished off a fifth of Crown Royal. Luck to survive that day as I remember speeding down dirt road and looking out a SIDE window to see where car was heading.
I see in your husband the same kind of man.
He died when I was 15. I didn't shed a tear.
He was found deceased by landlady in an apartment he rented - where he kept his paramour as I later found out. aneurysm on aorta - at least it was quick
50 years later - I am still working to learn to accept my lack of growing up in a family. Mother tried but she was a harlot herself.
Appears your two kids have a much better chance at growing up decently balanced mentally as you seem to be a good mother.
PS: Also didn't catch anything that day - other than a chigger bite or two -
Adding to say - I think your Dragons have it figured out.
Come to terms? Well yeah, reality sinks in.
Then the disdain at the thought of association will be realized. Some (like me) only went to his funeral - mostly for "family appearances."
