I also divorced my XH after a 35 year marriage (37 yrs together) for cheating.
He had cheated before 31 years prior and I know there were other 'dalliances ' plus he was decent looking, charming etc like yours.
We also got along extremely well.
I crashed on discovery day (Xmas day morning) and threw him out 2 days later. He defaulted and moved in with her. She wanted husband no 4 and played a superb pick me dance.
Without going into more details about that, I am now 2 yrs 10 months on.
These are the things I did over that period when I was deep in the trauma and shock. I lost 2 stone very quickly and just crumbled but the following things got me through:
I walked manically for an hour every morning just to unravel my mind
I contacted a great solicitor and got the ball rolling ( he refused to reply as didn't want a divorce after all apparently).
I had a yoga habit and continued to attend classes
I got some great talking therapy weekly online who helped enormously.
I learnt to roller skate ( great social thing too )
I contacted friends and made sure I went out every weekend somewhere so I could dress up and at least look good
I had an amazing friend who called me every day and just listened.
I did the new haircut, had a bit of face stuff done and bought some new clothes.
I booked a few long weekends away at spas and retreats and met other women at these places who'd been in similar and it was eye opening.
After 9 months I had a somatic therapy course which changed my life as it really helped me understand my emotions and feelings.
I saw my adult children / grandchildren a lot and still cooked for them when they visited and tried to be the strong mum they wanted me to be. A bit fake it until you make it I guess.
After 10 months I I felt strong enough to just see what online dating was like. Had some dates and dalliances but decided it wasn't for me but I don't regret it as I felt like a woman again ( not a wife).
At 10 months he asked me if it was 'too late for us?' and I said yes, you chose to live with someone else. He cried.
I was expected to do the Pick Me Dance ( as I used to do I realised) and refused.
Books I read that helped hugely were
'Leave a cheater gain a life' ( invaluable even if you don't want it to end) and I still read Chump lady's posts most weeks.
'Cheating in a nutshell' by Wayne and Tamara Mitchell was incredible.

After a year I went to India for 6 weeks, had a lust at first sight moment and now have a long distance lover who I see every few weeks ( he lives in a Mediterranean country) and I rediscovered my sexuality. It suits me.
I still have low moments and get very sad at times ( mostly from the rejection and cruelty he meted out to me ) and I now just have to accept those feelings as being part of me.
Financially I'm worse off but OK and I chose to have zero contact with him at all ( he tried to be friends and be flirty if we ever bumped into each other ) and my adult kids understand why.
I had to start again at age 59 and I won't lie, it's been incredibly hard. But staying married I would have had to suppress a lot of emotions and I now know how that can affect someone.
I found out that he's discovered the grass isn't greener just a different colour and he tried to split last year but wasn't brave enough. He's now entangled financially with the OW and I'm sure there are good bits in their partnership so they carry on but he looks dreadful. He's put on weight, drinks too much and has really aged.
The OW is happy as she got a man to fund her life and look after her.
I believe he'll cheat on her at some point as he can't help himself and loves to chase the thrill.
