Sophocles, Women of Trachis; Stay True to me

So I'm multitasking and cooking dinner while doing some typing. I often don't spend the time it takes to cook dinner in the kitchen but rather set things going and put on a timer. Sometimes it doesn't work out as planned, but I'm no good at standing around in the kitchen waiting.

Story
The Women of Trachis is a story about the consequences of Hercules' roaming, yet it is a more domestic story.
Hercules' wife laments how much he is away and how little he seems to care for his family at home so, she sends her son to find him, to see if he can get Hercules to head home for a while.
Hercules' herald returns to his home to tell of his exploits ahead of Hercules himself returning, telling the story of how Hercules sacked Oechalia, after being insulted, and that he brings home the town leader's daughter as a prize. His wife sees through the deception and knows Hercules has taken another lover. She thinks back to when she was rescued by Hercules from a centaur and his words on how to keep Hercules faithful. She prepares a potion for him of the centaurs blood and the poison of the hydra as a love potion and sends it to Hercules. Feeling guilty about the gift, she throws the remainder into the sunlight and it reacts like acid: the centaur had lied. she receives the message that her potion has killed Hercules and her son rebukes her angrily. She reacts badly and kills herself. Hercules returns home in agony and furious at being poisoned by his wife. His son informs him that she had not meant to kill him but rather was trying to make him faithful and that he had been killed by the centaur from beyond the grave as it was his instructions and blood that caused so much pain.

Reflections
The thing I first noticed was, how trusting Hercules' wife was of what the centaur had told her all those years earlier and how she can't have known the prophecy that he would kill Hercules. I just can't see any other way you would be willing to take the centaurs advice, even before knowing what it would do to Hercules, it seems like a rather unwise plan.
I also marvel at the arrogance of Hercules, to take another woman, when he has a wife and family at home but this seems to be common in these Greek plays.

Comparisons
We have seen Hercules before in the Shield of Heracles, but here we see him in less heroic and more domestic terms. We see the end of his life rather than one of his triumphs.
In some ways it also parallels Agamemnon in death being caused by the wife but it differs in that in Agamemnon his wife deliberately kills him because, he has take another to bed, where as, in the Women of Trachis, we see the wife is the one cheated on and the death was almost accidental or, at least, his death is an unforeseen consequence. We see in this play the wife's remorse compared to Agamemnon wife's lack of remorse.
