honestly I do see menelaus as an imperfect husband but I don't think he's abusive or hates helen, I think his problem is that he loves helen so much that he worships her.
the first time they meet, menelaus just lost his father and was exiled from his kingdom with his siblings, he just lost everything and now has to live with a stranger, but then he sees helen. beautiful, smiling, kind helen. yet to know grief or pain helen. too perfectly to ever possibly be a mortal, a mortal like him, helen. and menelaus is immediately drawn to her, he starts viewing helen as a goddess he is lucky to even be in the presence of, he loves her because she is everything he's not to him. she is perfection.
but helen isn't a perfect and helen isn't a goddess, helen is a person with her own flaws and pain, but menelaus ignores that because it ruins his perception of her. it ruins the fantastical illusion he crafted of their relationship as a mortal man and his goddess.
I think at some point helen used to view menelaus through her own fantasy as well, but her fantasy was childish and she grew out of it when she got older, menelaus' fantasy warped his perception of helen to the point he could never grow out of it, at least not until the war.
helen still loves him back, of course she does, he's her best friend and her husband and the father of her child. yet still after marrying him, something she used to always dream of doing, his love feels too strong, it doesn't feel like he listens to her, it doesn't feel like he genuinely loves her, it doesn't feel like how she imagined marrying menelaus would be like. he's not trying to be a bad husband, he's always showering her in praise, always buying her gifts, always around her, but it's to the point it feels like it's too much.
so much that helen starts to question their love, she still loves him, but their love isn't as she pictured it being, she wanted to be menelaus' wife, she never wanted to be his goddess. menelaus doesn't question their love, he thinks their love is eternal, he doesn't start to question it until helen leaves, because only then can he finally learn to let go of his view of helen as something divine, only then can he finally learn that she's a human too, imperfect just like him.
after all, worship is a form of dehumanization.
