Spent time in jail because of him and his mom

I started dating my now husband 2 years ago. He is a huge mama boy and I’m not close to mines so I let him have it and she is nice to me and always coming over spending the night etc. she pretty young too. Last week she came over and he asked me to go get some groceries and cook with her. I miss cooking with my mom when she was sober. So I did it. I get back and both of them are in the bathroom he always helps her because she has some type of knee issue. Anyway I went back in there to clean up behind them and I seen a towel full of nut. I know what my husband nut smells like. I’m not crazy.! But I assumed he just jacked off or something. We cooked I went to bed early and woke up early too. His alarm went off but it was a 3 am alarm for no reason ? I’m like whatever I pick it up to silence it. And his mom texts him “come on I’m in the laundry room hot n ready for you. I hurry up and go to the laundry room. (I’m a heavy sleeper but I was already up so that’s the only reason I even seen this) and she was in there fucking naked. I’m out of jail now and I just don’t know how to feel . I’m at a hotel and I’m reevaluating my life now. We don’t have any kids. Should I confront him? He sent me a thousand “it’s not what you think” messages. Please help

Someone asked why did I go to jail and herrrre we go:

Well when I seen her naked I grabbed her then I quickly let her go remembering she had a bad knee then I circled in one spot panting then I literally pulled some of my hair out I went to his room woke him up and started yelling at him. In the mist of me yelling she fucking comes behind me and throws a whole lamp at me. I lost it he lost it and I went to jail. I blacked out. I have stitches in my scalp as well. But she now is claiming I have been abusing her and he is texting me telling me he wants nothing to do with her. I’m facing charges now felony charges. When in reality she hit me and barely has a black eye…
