I know that I have my own problems and s hould be the last one to comment but this part made my blood boil.
"I'd like to just take some time for myself. However, I feel like if I ask for that, our marriage will be over. I don't see him agreeing to that at all."
uhm, so he can go and have another A and he expects you to just deal with it and believe his BS words that "he'll never do it again" when he already sang that tune 8 years ago? The way I see it, you should do what YOU want to do. Take time for YOU. When you are well enough and strong enough to deal with him and decide what you want, then so be it. but it should be on your terms, not his.
I am so sorry you are going through this. I have an H who had an affair too and my worst fear is healing from this, only to have him go out and do it again.
I pray for you and your strength.
