Two months is too soon to expect it to get better. My wife cheated on me 15 years ago, and it took us over a year to get to where our marriage was actually better than before the affair. Not that I'm recommending affairs, ours could have been better if she just talked to me.
Your husband is hurt more than you can ever imagine. He feels emasculated, he feels betrayed by the one person he thought he could trust.
If you truly want to heal your marriage, get some counseling, or buy some really good books, because your marriage will not get better until you "get it".
You might think you understand the amount of pain he's in, but really you don't. You've never experienced. It's the worst.
The single best thing you can do is be honest with him. Read about "trickle truth" and how hard it is on the betrayed. Answer all his questions, no matter how many times he asks. Don't sugar coat things. Don't let him end up like me, still finding out things 15 years later.
Once he knows everything, he will get angry, hurt, you name it, but he will start to heal if he feels empathy from you, not inpatience.
If he is constantly hit with new information, he will never heal.
