So - doesn't this mean he (mis)interprets your pleas as you not loving him and valuing him?
What would happen if, instead of asking him for the things you want, you asked him what you could give him that HE wants? (Don't whack me yet!!!)
What if you wrote to him: "H, I realize my requests for things I want in the R make you feel like I'm not happy with you and don't love you. Since this isn't true, I'm realizing that I must not be doing the things that would make you feel happy and loved. (And obviously, isn't that what we'd both like, to feel happy and loved?) So I'd like to ask you, what could I be doing differently or better in this R that would contribute to you feeling happy and loved?"
