Honestly, I viewed hysterical bonding as a net positive. I didn't really have the break you did though, I was doing it (ha!) before I ever understood what it was called. Learning that HB was a thing actually made me feel less guilt about it all (I had some shame that I was being a pick-me, spineless, weirdo by wanting to be with him at all before that).
It was a tiny bright spot and piece of connection during a period of turmoil and grief and misery. Just lying together afterwards - even if I cried, and that was not uncommon - involved some little oxytocin burst that helped. I don't think either of us believed that it meant that things were okay - things were clearly, DEMONSTRABLY not okay. But it felt good to have light moments. I had to check in with myself regularly during that period, to be make sure I wasn't doing it for him or to try to love bomb him back (definitely wouldn't recommend that). I think there were times where there was an element of me being territorial (I liken it to a dog marking their property), but mostly I was doing it because I wanted to and it felt good in the moment, and lord knows I needed whatever help I could trying to feel good during that period.
Another reason I'm kind of glad I did HB, was that I feel like we got that out of the way and avoided a scenario where sex turned into some big symbolic momentous thing. I have read stories about some BS who really struggle with the sexual aspect in R and feeling like their physical attraction to their spouse was totally gone, and I'm not blaming them for any of that (we all react to trauma differently), but I'm just grateful that I didn't have to go through that as I had enough on my plate. Don't get me wrong, I had my fair share of sexual hang-ups and triggers and mind movies throughout it all that came on unexpectedly and without warning, and there were many MANY times we stopped midway through and I cried or yelled or retreated. You will have them too I assume, that is normal and it comes with the territory. But my experience has been that the best way to get through/past triggers is simply to face them head on (preferably in a safe, controlled environment), rather than simply avoid them. Avoidance has its place and utility, we can only handle so much at a time, but blanket avoidance doesn't encourage or facilitate coping.
Again, this was just me and my experience. I was able to separate sex from love-making (for me, hysterical bonding was definitely the former rather than the latter). If you are worried about your ability to think clearly if you are sleeping with him, I would maybe make a point of proceeding more cautiously than I did (the fact that you're even making this post, suggests that you've already proceeded far more cautiously than I did ). As always, be sure of doing regular check-ins with yourself and your spouse, to see if you are able to be objective with where you're at. You can always change your mind if you need to.
