I am sorry things are moving so quickly. Reread your DR book and try your best to focus on you and not what your H is doing. It will help you to grow as a person for yourself and for future relationships, with your S or someone else.
I understand how hard it is, if it were easy we wouldn't grow. You can only control you and you are allowing your H's actions to dictate your mood, your growth and your future. I know it is easy for me to say not being the one in your position at the moment. I have been through many, many BD's over the last 6 years. DB and DR have permanently changed things but that is because of the change in me, the insight I gained and the realizations it brought me.
There may be a time where things work out with your H, however, he has to see a new you in order for that to be possible. Right now he is seeing you trying to hang on and slow things down and that will not bring him back.
Hang in there. I know this is hard - I am already D'd once and I have been through it, I know it isn't easy but know we are all thinking about you and sending positive thoughts to you.
