Read the five love languages. You weren't speaking her language.
My H cooked me dinner every night, planned trips, did a number of things to show he loved me, told me how he did these things to show me he loved me...and yet I felt unloved. I thought I was crazy, or being manipulated. How could I feel so unloved (and un-liked) if my H was doing all these loving things for me? And he felt the same way, even though I thought I did loving things.
