Interesting.
I respect him more for supporting me through this horrible thing I've done.
I really do love him, and the family we have.
If I thought it could improve with a confession I'd do it.
But I think DH would be insulted that there was something lacking in him. It would make him feel worse about himself (needlessly as nothing was ever lacking)
In my head I have started a 2nd chapter. Not hysterical bonding but a deep trustworthy love.
I have no secrets. He knows my passwords.
He's always been brilliant (not a walkover) but makes my morning tea/ de-ices the car etc. I've stepped up by being more present and mindful.
We've always got on well and had a shared sense of humour so I've made time for stuff that engages us - even through lock down. Funny videos on you tube etc.
But not just the 'actions' but the conversation and shared future plans. It's all there.
If I confessed I know I'd be giving him a burden because the 'right' thing to do is split but that is unlikely to be the best thing.
Working through it would be all very well but I feel it's my job to do that. Not his. He doesn't need to change a thing.
