Great job listening to what she is wanting and then being willing to give it to her. I know it is hard to feel that her needs are coming before yours. But you can do this, and you have worked hard to get where you are.
Unfortunately, for a lot of women, the sex is not as important as it is to a man, well, I don't mean that exactly. I guess some women know how much it means to a man, and a woman sometimes wants a man to show HER love in other ways. Clearly her LL is not physical touch like yours is, hers may be gifts and quality time. And until she can grow in such a way to understand that love is what you give to the other person, she will still be stuck in a me mode and expect you to give her her LL, without reciprocating yours. Try to look at what you give her as a gift, something you would not expect anything in return for.. simply something you want to give to her. And give her what you think SHE would want, not what you want to give her.
Please be careful with the pulling away, you don't want her to think you are pulling away because she won't give you sex... a tit for tat thing.
Relax. Appreciate. Be calm. Laugh. Enjoy. Be secure. Be loving. Be loved. Don't personalize. Don't ASSume. Accept. Be grateful.
