OP I do consider what happened now as a 'rough patch', but one that has made us far stronger and happier and much more of a unit than we ever were (and things were pretty good before all this). We, like you, also have approx 20 years together.
I have friends who have been through this since, the DH has acted like a total dick, completely rewriting history, denying an affair despite huge evidence to the contrary, barely staying in touch with his DCs and making comments like 'we were never a team' on one hand to his DW, whilst also telling her that he thought they would get back together one day.
It makes me actually feel proud of DH for stepping up, working on why he had an affair and being so completely committed to us now. He says it would have been far easier to leave and run away from what he did, not face up to it at all. (Believe me, I gave him hell, which he deserved!) But he didn't. And he is very happy that he stayed.
spadequeen Yes I was ridiculed for even thinking about staying together at the time of my thread about DH's affair. There were a lot of v harsh posters, but also some amazingly supportive posters and it was ultimately very helpful.
I listened to Prince Harri and another man talking about the Invictus games on Radio 2 last week. The other man was a soldier who had been injured and then took part in (and helped organise) the last games.
He spoke about how, when he looked in the mirror, he always thought of himself as an 'ex-soldier' after his injuries. A very negative way of thinking, he said.
The Invictus games gave him the chance to think of himself as something more positive - an athlete.
For months and months I thought of myself as a betrayed wife, the wife of someone who had an affair.
Now, I think of myself as someone who is very much in love with her husband and he with her. I look in the mirror and see someone in an equally happy, loving, affectionate relationship. Why dwell on the past, when the future looks so good?
I will always know what he did, but it doesn't make me a victim or 'defeated', thanks v much.
I'm strong, independent, have amazing DCs, a job I love, lots of friends, a fab hobby (at which I have a real talent) and live a very fulfilled life. My relationship with DH is in addition to all this.
It's not been an easy path, but time is a great healer. It's a cliché for a reason.
Good luck OP.
