I know from the experiences of other men how difficult that was for them, but that's because you're talking 'frame'. I internalised an IDGAF attitude when I was sixteen and almost killed myself, so after aborting that, I prioritised myself and my personal opinion over everybody else's. I made a turnaround when I was 23 after almost getting stabbed to death and mellowed out a bit, but not on my ethics. So I have no problem negotiating and compromising in order to work together, but I had strong boundaries.
I married a Christian virgin girl ten years younger (23 while I was 33) and we were together for over sixteen years.
My divorce came a year after I became severely ill and my wife couldn't handle the emotional pressures I had shielded her from and allowed negative girlfriends talk her into divorcing me and 'starting a new life'. She since seems to have regretted her decision ("I wasn't in my right mind"), but I'm glad I got to see her true nature. I'm happier now than in the last years of my marriage, I have three lovers on rotation and none of them gets to go exclusive with me, but they understand and they don't mind sharing me.
Before I married my wife, she knew I never had a problem juggling 2-3 girlfriends, openly polyamorous and non-exclusive. I never needed to use 'dread game' because my wife knew I was 'good with women'. Still, I sensed a lot of bitterness from her how easily I picked up my life post-divorce while she went through 4-5 'new life partners' in the span of a 18 months. I know she's less happy than she expected to be (she often claims to be in 'survival mode'), but IDGAF as she brought this on herself. Meanwhile I got better and while I still have chronic pain issues, I have no trouble finding women to share my bed and enjoy my company without the urge to re-marry. I'm perfectly fine with living alone with my teenage kids and I'm not going exclusive with anyone, so if they choose to be with me, they know they have to share. My ex-wife has a hard time living alone and gets from one relationship into the other, although her current relationship has been going on for over a year now. She still tries to get me to act like her husband sometimes, but that time is over. I don't have a 'frame', but I always preferred to be alone over being in a bad relationship, so when my wife wanted to divorce, I was only concerned with protecting the kids (6y + 9y at the time) to make sure they wouldn't suffer from the divorce.
