FairPlay you have handled this so amazingly! I wish I could have been the same (my world fell apart exactly this time of year, kids were older but still a struggle and I even thought of trying to ‘get passed it for the kids’ /financial reasons/ and frankly being terrified at having this happen and not knowing how to locked with such upheaval, even though deep down I knew I could never ever trust him or love him again). My ex was the same, barely asked how the children were, very in denial about the severity of what he (and my ex best friend) had down for the best part of a year, as if it could all be forgotten.
I don’t think your husband ever had any intention of leaving, I think he probably enjoyed the ego boost etc. my ex’s excuse was that I’d stopped asking how his day was…. Don’t listen to any excuses, no matter what he could say, it will never make up for what he’s done to you and your family, but I can pretty much guarantee he will be sorry very soon and regret this for a long long time.
on the other hand, you have nothing to regret. You sound so strong and have such a lovely support network, I’m not saying it’s easy, but you will get through this and be happy in your new normal. How you’re handling things for yourself and children is so admirable, I hope the birth all goes well and you and your family will be able to make the most of Christmas and a much better 2025 than what the end of this year has thrown at you
