Is it odd that I’m still in touch with my friend who my wife cheated on me with recently?

My wife recently cheated on me with a friend of mine, who also happens to be an ex of her. They dated briefly for like a month but were fwb until I asked her out. We’ve known each other for over ten years and recently my wife cheated on me with him. Although my wife cheated on me, it was totally my fault. A week ago I met him, spoke to him normally and he apologized as well. We’ve been in touch ever since. Is that normal?

For the record, I’m still married to my wife and I’ve moved past what happened because I love her.
