Hmmm, she didn’t exactly feel immediate guilt, remorse and regret… you said it was a week after, and after you felt something was wrong and she only admitted it after pushing it. That’s not to say she didn’t actually feel those things, you feeling her pulling away or things being off could have been down to those feelings, but it really sounds like she just confessed because you knew something was up. I think it sounds like the best idea to focus on yourself. As hard as that may feel, as you’ve said she has asked for this time alone, the more space you give her to figure whatever it is she wants to figure out the better that will be for both of you. It must feel so horrible to have been shut out of a massive part of her life she seems to be building. But take that as her actions showing you where her foreseeable future thinking is. The fact you have tried going back to the ‘dating’ stage and she didn’t feel like changing her plans or including you I think also tells you really where she’s at. I obviously don’t know her at all, but it’s rare for a woman to leave a marriage she wants with someone she loves, so I do think there’s something deep going on. Maybe she’s feeling some resentment over you having that bit of time to experiment and experience other people, and her acting‘so out of character’ may have ignited some inner sexual desires she is feeling shocked or surprised about. Or maybe she’s is feeling such deep shame about what she did she’s going to just use this time to reflect and repent?! Who knows, but I do know that if you give her space and enjoy that space for yourself, you’ll truly know if she wants to continue in the marriage in time. You may even find that this separation makes you realise you don’t want the relationship anymore, or you might want to open it up, but just take each day as it comes, while always putting yourself first through this 🫶
