Angelic:
You say: "my husband has been pushing me into it for myself to make me all better".
I think it is important to get your thoughts as clear as you can. I do not get the impression that there is anything wrong with you that would require you to get "better" (?). It is your husband, not you, who has got himself into a situation, and this is no fault, absolutely no fault, of yours.
He made the decision to philander, and that was no one else's decision but his. I get the impression he is projecting onto you, to try to blame you in some way for his wandering. Is this so?
Do not allow yourself to be demeaned, to be left as some kind of "second option" on one side, while he is making up his mind. You are his wife, you deserve some respect, and he is not being respectful.
Naturally you would want your marriage to work, but he is the other half of the marriage, and will need to get in tandem with you to work on the situation.
A well-qualified counsellor will help you to see things more clearly, so that you can work out for yourself what exactly it is you wish to do.
Have you asked your husband to attend counselling with you?
All the best
