When Michael had to abruptly exile himself to Sicily after murdering McCluskey and Sollozzo, he was in love with Kay and she with him. (Well, I believe he loved her, even though he was too embarrassed to say it over the phone with his mobster cronies around .) Yet while Michael is in Sicily, he falls in love with someone else and marries her. I would think that this would be difficult to do if one has feelings for a special sweetheart back home.

At the beginning of Part III, we learn that he and Kay must be divorced, since Kay has a new husband. Why didn't Michael remarry? (GF3 is not particularly memorable to me, but I'm sure I would have noticed a new wife.)

What I find rather unusual is that Michael had no problem marrying someone else when Kay loved him and was waiting for him back home. Now that their relationship is somewhat estranged (only kept cordial for their children) and Kay will certainly never be his wife again, he did not take a new spouse. It seems so out of character because I thought he was the marrying kind who wanted a family around him. I don't know exactly when Kay divorced him, but I assume he would still have been young enough to have children with a new Mrs. C. Children seemed so important to him. Any thoughts?

And on a side note, did GF3 indicate if Kay had had children with her second husband?

And on another side note, did Michael wear a wedding ring in GF3?
