I know you are frustrated and that you want more out of your M than you are currently getting but I really believe your W needs time. I would stop asking her about the massage because she probably feels pressured.
I know you feel like you have been doing everything for her and she hasn't been returning all the loving feelings for you. Well what about doing more for yourself right now and backing off from your W in a loving way. Don't try to make everything so great for her all the time as that is what is draining you. Step back for awhile and don't make any harsh decisions. Just remember how far you have come and months ago what you wouldn't have given to be where you are now.
I think things have moved pretty quickly for you and your W so you have remain patient and focus on yourself.
One other thing - not to come down on you hard, but when I read your posts lately I think you are pushing and pressuring your W, not necessarily for sex but for touch etc. I think you have to back away from initiating anything and let her come to you. She is coming to you by cuddling etc. so let her continue to come to you so she doesn't feel so pressured.
