Just need to vent

It's been nearly a year since my fiancee and I have had sex. I have talked with her about it many times, to the point where I feel annoying when I bring it up now. When I first brought it up, she said that she didn't feel connected with me enough in other ways, so I attempted to accommodate by getting her gifts and asking about her day, etc. When I have brought up the topic of our sex life more recently, it seems like something always prevents us from having any kind of physical intimacy. I can't even recall the last time we've made out. It just feels like she stopped trying a long time ago, and so I've stopped, and it's hurting my self-esteem along the way.
