It was determined earlier in this thread that Jason is divorced. I know a fair number of divorced people, and only one left the marriage with anything less than deep regret and agony. So the only thing I will assume about Jason in that regard is that he has experienced heartache. And I assume that the aunt is filling in for Jason's part of the custody arrangement. If it's shared custody, the mom probably has a job or some activity like advanced schooling that makes it more reasonable for her to have less-than-full-time custody even when Jason is away. Anyway, he's bright and seems honorable, and I'm sure the arrangements existed the way they did for a good reason that is not any business of mine.
Whew! Having said all that, I like him so far and I will be quite pleased if Dee ends up with him.
