Stop thinking of this as a 'pay back.'
Was your pregnancy a surprise?
IMO, there's not much to worry about. They guy proved to you that he wanted to be with you. Why would that change now?
I have several friends (girls) from back in the day and we call each other "honey", "love" and/or "baby" out of a deep love we have for each other, we send kissy faces all the time. But we're friends and friends only. There's nothing more there.
Why would there be something more in those chats? Is your husband behaving differently with you? Did he change from a loving husband to a heartless cold man that comes home late from work every day?
There are clear signs that can tell you if he's cheating or not. Going through his chats is not the right thing to do.
Good luck, take care. Your baby is first!
