I did. He had an affair about 7 years ago- I also had just had a baby, so reasonably similar circumstances, also kicked him out for a while.
It helped enormously that he didn’t try to hide anything. He knows I’m like a dog with a bone and I’d get to the bottom of it anyway, so I got full disclosure and saw all the messages etc. It was very unpleasant, but as I said to him, I can’t forgive you if I don’t know what I’m forgiving.
I also think it helped that I didn’t make any kind of decision right away. After he moved back in because I was finding it exhausting with the baby, it was on a housemate basis for about a year. I made it clear that any pressure to decide about being a couple or any crying or moping and that would make the decision for me. He’d unilaterally decided to cause chaos in our relationship, no way was I going to be the outlet for his distress. So, I had time to really, properly process it all without muddying the waters with still sleeping with him/being ‘coupley.’ This was difficult, as my initial instinct was to want intimacy and closeness for reassurance, but actually I think that was probably the last thing I needed if I wanted to approach the situation with a clear head. I was aware that he was hoping that I would choose to stay in the marriage but to his credit, he never pushed me at all and spent the time doing his best to be a supportive co-parent and making sure I had the time and space to heal.
I spent that time focusing on building a support network, nurturing old and new friendships, improving my health (as well as of course enjoying my new baby) because I wanted to make sure I had everything I needed to cope on my own if I decided the marriage wasn’t for me. That was a big source of strength, because I knew that even if the worst happened and he fucked up again, I had everything I needed to thrive.
I also took the opportunity to reset boundaries around housework, support for my career, and other things that I felt were unbalanced even before I found out about the affair. Once we decided to get back together, we did a long-distance move as I was unhappy where we were anyway and wanted a fresh start far away from affair partner and people connected to her. It was just too awkward worrying about bumping into people. My take on it was ‘you’ve spent the last however long doing what you wanted to my complete detriment, I think it’s time we prioritise my happiness and comfort for a bit.’
This probably sounds cold but I saw it as an opportunity to change my life for the better- sort of, this cataclysmic thing has happened, but this might be a chance to rebalance things and build something new instead of plodding along tolerating things I wasn’t really happy with.
I honestly think it’s partly down to personality too. I’m just a massive pragmatist and kind of looked at is as, this is shit, but these things do happen, and it’s no reflection on me. I just wanted the best outcome for me and my child and wasn’t going to make any decisions in a hurry.
My decision and feelings about it would probably be different depending on how he handled it. I’ll never excuse what he did, but it helped that he never tried to rewrite history (for example, he didn’t try to claim that he’d been unhappy in the marriage etc) and he immediately cut off all contact with the OW and everyone connected to her. He then made permanent changes to ensure I felt supported and never put any pressure on me to have him back. Those changes have endured ever since, and if he hadn’t done all those things then we wouldn’t be together. You can never say never but I don’t worry about it happening again, it seems to be genuine change as it’s lasted for years. He was a pretty shit husband pre-affair tbh so it’s been a pretty drastic turnaround. His commitment to changing without any guarantee of getting back together did help me regain some respect for him.
I genuinely don’t feel upset about it at all any more. We talk about it openly without anyone getting upset or defensive if it comes up, which it does sometimes when we’re reminiscing about the early days of parenthood.
I’m really sorry you’re going through this OP. If I could give you any advice, it’s that he must be honest and really understand the impact it’s had on you, and you need to fully process it and take the time to decide what you really want. He’s changed the landscape of your relationship with his actions. It won’t ever go back to how it was before- it can be forged into something new, but only with huge amounts of work. In my opinion, with him expending the most effort, as none of this is your fault.
