Just venting

My husband cheated on me. I took him back. His little whore keeps messaging me and telling me about their sex life. This was almost a year ago. We had decided to move on and now I'm pregnant. I don't have any rage or resentment, but I noticed we no longer have a sex life. We don't cuddle. We don't kiss. We're so plain. I feel hollow when he's here but I miss him when he's away. I sound like "one of those women" but after 8 years... I'm not sure what to do.
