Bunny, anger is an emotion and is very healthy! We have to feel our emotions or then we will get sick. If you are angry at your husband, your body/anger is telling you to do something about the situation.

Why do you stay with him/take him back? The only accountability he has is to you and your marriage and if he does not seem trustworthy to you, what is the purpose of being married to him?

The anger is not going to go away until you solve your problem of what do to in your relationship; your husband isn't angry because he already decided to have an affair. You have to decide your half of the situation. Just feeling isn't doing.

If you do not trust him I would ask him to leave, at a minimum and, depending on if you want to continue the relationship or not, either work toward getting a divorce or tell him to show you, by his actions, that you can trust him again.

I am sorry he hurt you. There is nothing you or he can do about that now; it's done. Now you have to deal with the next step, I think that is what your anger is telling you.
