Is it ever possible to move on from cheating (not physical but as close as it gets)

My SO was talking to another woman he met on Facebook. Conversation became intimate. She sent him nudes. He praised her body in them. Saved them to his phone. He never sent her anything. He didn’t really encourage her but DEFINITELY didn’t discourage her. Their little text relationship went on for 2 months though. He only ended it when she tried to add me on Facebook saying it would turn her on to be friends with me while knowing he would choose her over me. I didn’t add her because I didn’t know her but she told him she tried to add me.

We have an 8 month old baby together and he admitted to her that we’re never intimate anymore (that’s not MY fault but he made it sound like I didn’t want him and that’s why).

I found out about all this when he ended their months long convo and blocked her because then she sent me all the chat screenshots.

He’s very sorry. His apology was sincere. And he’s committed to working through things. He admitted it was solely his fault and I’ve been nothing but amazing as his woman and our child’s mother.

I just don’t know how to recover from this and trust him. I never imagined he would do something like this in a million years and now I don’t know how to get over it even though I agreed to give him a chance.

Is it possible? Honest answers please, if you’ve been through this and stayed, did you ever trust again?
