He's telling her that she has overrated her own capacity for guiding their relationship. She has actually turned his life to something darker and he has realized she will take him to a nervous breakdown sooner or later if he insists on letting her to guide him. I assume he thought she was the cure that he was needing for healing his own emotional hurts at a first impression until the day he could see she is sicker than him indeed... So now he's trying to take himself to a 'better place' and he hopes that she will follow him ("What needs have been / You'll realize / I've found myself / In bluer skies"), specially because he knows how much she needs his support ("Can we dissolve tonight/ Held by your hungry arms").
