On a family holding with kids (aged 20 & 16) i was poorly with vomiting and sickness. Dh got friendly with another couple who turned out to not be a couple, just work colleagues. When i started to feel better my gut felt off about this other woman in the couple. Night before we flew home dd got ill so i took her back to her room. Dh stayed out with ds (20). At 2am i woke up and he still wasn't back. Texted ds but ds was in bed. My gut felt off so i got dressed and went out looking for him. He was sat in a bar with a group. I stayed and watched for a while. When others in the group left, dh was there with just this other woman. She got up and pecked him on the mouth. I carried on watching from outside. They sat there talking and he was holding her hand. I stayed to see what else might happen but then others in the group came back so i thought that nothing else was likely now they had company. I went in, told dh that dd was really unwell and he needed to come back.
He is very remorseful, says he felt sorry for her as she was telling him bad things that had happened to her. Knows he crossed a line, is remorseful but also minimising it as he doesn't feel he's cheated. I know it's not much in the greater scheme of things, but it's made me not trust him. Like how was it so easy for him to do that in a couple of days whilst i was ill with some random whilst on a family holiday? What are the chances this is first indiscretion and i just so happened to uncover it? We've been together for 22 years. I would never in a million years think he'd do something like this. I feel like i don't even know who he is and not sure if i can reconcile it in my head. Doesn't seem like something to end a marriage over, but equally, will i ever feel 100% like i can trust him again?
