I'm sorry you're having a rough night and I'm sure many of us recognise that feeling of unbearable pain and the desperation to bring pain to an end. The main thing is not to act on it and recognise that in time things will improve and you will feel better. And actually, having experienced pain like that helps us to appreciate the little things in life and live in the here and now.
Yes, try not to mind read - I doubt very much that's how the evening unfolded! Now we are D'd it may well be that my XH is busy planning a wedding and new family...but if that is with OW, they will always need to live with how their R began. And I'm not sure that true happiness can really be built on that kind of shaky foundation.
The main thing is to try and haul your focus off them and onto you. Try and do soothing things that occupy you for a little while, spend time with supportive people and so on. This is a further BD for you and feels awful - but on the positive side, we tend to recover much more quickly from a further BD than we did the first one.
I'm hoping you will drift off to sleep soon and wake up feeling more settled, and have a better day tomorrow.
This too shall pass xx
