Gawd, Hopper! I'm sorry you know these details. I found out about OW#1 by reading three months of emails between them. Then H set up a secret IM account for them. I still found out her telephone nr. and called her. This was 7 years ago. H wanted back in, but couldn't deliver. Now, I think he's cheated again, many times and longer then even I suspect, just because of his distant behavior. It's just a feeling, and I won't follow up on it. Not worth the trouble.
You're expecting? Darn, that must so weird, wanting the baby, but sad about her/his father. You sound like a strong, brave woman, and you'll get through this. I do understand about wondering if he's cheated throughout your M. I've thought the same, and I'm divorcing my H because I know I can never trust him ever again. If he had made an honest attempt at R, it might be different.
Take care.
