Your right, you should not have done this. Have you gotten into IC for yourself yet?
You need to find another way to release your anger. Join a gym. Buy a punching bag. Take up running.
Don't ever hit him again. Not only because it's not ok..but he can call the cops and have you arrested...and you would go to jail.
An affair is abusive. Physically, mentally,and emotionally. Bringing more abuse into the situation will only make it worse.

..that feeling you get in your stomach, when you heart's broken. It's like all the butterflies just died.
Your right, you don't want legal ramifications. So let this show you what this is doing to you emotionally, and figure out if you can afford to stay in this situation. Maybe this was a dealbreaker for you. If it is going to affect you in such a way that this happens then you need to take a close hard look at what you can take.
Get into counseling and start working on you, if your H is working on him then let that happen and step away from the M a bit. Cool off.
