Ok, I'm sure it was a lot more complicated than that. In fact, a recently discovered poem by Hughes describing the night Sylvia Plath died gives us a glimpse of just how complicated it all was. It's hauntingly beautiful in a way only hommages to tragic love affairs can be.
I pity Assia Wevill (mistress-turned-wife) more than any other character in this tragedy. She committed suicide by placing her head inside an oven a la Sylvia Plath. I imagine Plath would be a very tough act to follow. How very Rebecca it all was!
