(EDIT: for clarity, my BS is non-binary and their pronoun is 'they')
Background:
In August 2018 I had an ONS equivalent with a colleague at a work conference. I have been with my partner for 7 years to date. We are engaged. We had a fantastic, intimate, fulfilling, good sex life relationship. They had a difficult family life, and I was their first really positive attachment. It is the first long term relationship/serious relationship of any type for us. There was one prior act of infidelity around the 3 year mark that was confessed immediately - it was more ambiguous and less damaging than the ONS, but still forms part of the pattern/history, and mistrust that my partner is currently experiencing.
What makes the ONS worse is that we were partly non-monogamous at the time, but had a rule about only sleeping with strangers. At one of the post-conference parties, this colleague who I hadn't met before was coming on to me. I called my partner to check if they would be comfortable with me sleeping with the colleague. They said no, as in my organisation people move around a lot so the colleague may not be a stranger for long. I didnt do anything that night, despite being quite drunk. But the next day, while sober, in the middle of the afternoon, I went up to his room (having told him we couldn't do anything!) and we then fooled around. On reflection, I know this was the result of a stupid attraction to boundary pushing, to the point that I ultimately made a decision I now regret hugely.
I felt terrible straight after, left the conference, told my partner. They were shocked and upset, but we quickly set about remedying it. They asked me to do three things. I did two of the three, but didnt do the third (going to therapy - so so stupid I know). We moved on mostly, and didnt really talk about the infidelity much after that - although it came up when the work colleague moved into our 10 person office. After some cajoling, I spoke to the colleague about how much I regretted the episode and that it was a huge source of shame for me and hurt for my partner. I didnt offer to quit my job which I find very fulfilling - although in retrospect I should have offered this.
Now:
Just before the one year anniversary of the infidelity, my partner started having dreams about the infidelity, and gradually having increasing bodily reactions to it (like a PTSD response). These dreams became bascially nightly (or about abandonment in some other form). Eventually they stopped being able to have sex with me, without it being a traumatic experience. I confess I was sort of in disbelief at the delayed response. They had a lot going around in other realms (work issues, friendship issues) and I thought it would just pass, or that they were having a disproportionate response. I now realise this is quite a self-deluding hope/redirection of the impact of what I did.
We started couple's counselling and eventually (again after cajoling) I started IC. We recently changed couple's counsellor, but are still in couple's counselling. We have talked at length about the harm caused, the whys, the different ways it hurt and continues to hurt. They also started IC for this and other issues.
We had a big conversation recently where they said they felt like they were leading the whole thing and I was just walking behind them; doing what they asked, but not volunteering much at all. This is certainly true.
They put me onto this forum. I've found it really helpful in reclarifying the huge wound an ONS can cause (I think I was in denial about its impact because the transgression felt so much less than a full-blown affair, so I found it hard to connect to much infidelity material). In quite recent times, I've become more proactive, and they've noted it, but I'm conscious that it's so late in the piece.
My partner is in such pain that they've set a six week deadline for us to decide what to do. That ends on the third week of March. We are basically at the point (we have lots of honest conversations) where we understand that they are pretty much seeing if they can feel any different at that point, because if not, the situation is intolerably painful and they need to break it off. They are still having abandonment dreams, still get extremely distressed at any sexual contact. While they are not as distraught as they once were, they have explained that part of this is borne of a feeling of numbness. We still sleep in the same bed, and they like to be spooned at night by me. We do not have big fights, but are open and talkative with each other.
I just want to make them feel safe and trust me again but I don't know what else to try. They are largely put off by physical affection, although it's there when they need it and is constantly offered. I have stepped up my domestic game (cooking, cleaning, mental load stuff). I've spoken to the colleague (especially as my partner now works for the same organisation) again reiterated that I don't want to even be more platonically friendly in the office with them than is strictly necessary. I have offered, genuinely, to change my job.
I know that's it's ultimately their choice, and it may be that I've simply done too much harm (in the initial act, and the subsequent laxness) to enable them to want to continue with the reconciliation. I just dont want to leave any stone unturned. They are effectively run out of ideas as well, but I have energy and desire and still want to put forward whatever is possible.
Thank you for the long read, and any advice.
(I am 28 - my partner is 31. No children).
