I'm so sorry for what your SO is putting you, and the little one, through. I want to share my experience, because I've gone through something similar.
My husband of six years got tired of me working out of town. He got bored with me, and wanted to be with other women. I thought he was the love of my life. I've known him for almost 30 years.
There were so many red flags during our marriage, going right back to the beginning of it, that I ignored because I loved him so much. I could have saved myself so much time and pain if I had not pulled the wool over my own eyes when red flags first started popping up.
At the end, he literally dumped me over the phone, one day after meeting the OW and telling her that he was single.
Like you, I exposed - and like your SO, my husband was ENRAGED. He lied to me, blamed me, called me crazy, and trashtalked me to his family and our mutual circle. Most in the circle abandoned me by default, because I met them all through him. It was horrible.
After he left me, I found out about horrible ways he'd treated women who came before me, including his first wife. But I stood out, because I was the first woman to ever call him out on his bad behavior, the first woman who exposed him.
Now he hates me, has completely ghosted me, and will probably never speak to me again. Yes, it hurts, but the reality is that if he had truly ever loved me he would never have mistreated me or betrayed me to begin with. He promised never to lie to me like my first husband did. And yet, that's exactly what he ended up doing, over and over.
A remorseful spouse does not fly into a rage when their affair is exposed. A remorseful spouse who wants to reconcile or "fix things" as your SO said she wants to do, does not move out of your home and separate from you.
Everything is crystal clear now that I have had more than a year alone to think back on the six years of lies and betrayals. But I understand your pain. I understand the conflict between anger towards your betrayer and a longing to be in their arms getting comforted, a need for the pain to end.
This will hurt, but please understand, based on everything you've posted, it seems clear that your SO is not remorseful and does not intend to stay with you. She may be throwing you crumbs of hope to keep from hurting you more, but it's clear from my perspective and similar experience that she is not a good candidate for reconciliation. She is stringing you along.
I'm a lot older than you. I wasted my whole adult life loving this man, forgiving him over and over for big and small hurts, only to be left alone, unable to get back all of those wasted years.
Please please leave her. If she truly finds remorse, it will be crystal clear from her CONSISTENT, transparent conduct and accountability. If she truly loved you, you wouldn't have to wonder. You'd know.
Take care. I wish you all the best.
