What a trying time for both of them. If one parent gives "too much" in one direction to come to terms with what happens to a child and the other doesn't give what some might consider "quite enough" then tempers can flare, emotions can run like the waves in the ocean, and resentment can set in, even finger-pointing.
For example, Jug could feel she doesn't spend enough time with him; he could think she should move on with her life and be a wife to him and a mother, too.
It's like the saying "being between a rock and a hard place", which is never comfortable.
I remember the movie "We were the Mulvaneys" about the Catholic high shcool girl who gets r*ped by a jerk from a powerful and wealthy family. It tore the entire family apart. And although it's a different situation, it's roughly the same outcome.
Prayers for Beth and Jug, so that they can each find serenity in their lives.
