I can't agree that Helen had family support she should have turned to before getting stabby. She painted herself into a corner by alienating her family by threatening to withhold Henry from them. Then insisted the family accepted Rob as this wonderful, considerate man which she thought he was at that time. By the time things started to go wrong for Helen, Rob has charmed Pat into agreeing with everything he said and did wrt Helen and he was doing a good job of convincing them it was Helen who was unhinged. Effectively they we collaborating with Rob with the best of intentions for Helen.
-serves her right for being a spoiled brat--
