Sex refusal: Sex is a personal and a couple decision. It's important that you focus on increasing emotional closeness, resolving conflicts harmoniously, and communicating well. Your doctor can look for medical causes to lowlibido & offer a referral to couples therapy. A licensed professional can guide you in talking about what is causing inhibition and what to do to fix it before the relationship is damaged.

Decreased libido: You sound concerned about your loss of libido -- or at least your partner's reaction to it. Libido can change for many different reasons. Difficulties in the relationship can express that way; also depression can decrease libido. See your physician for a health evaluation if you haven't had one recently. Also consider seeing a psychologist to explore what's happening with you & relationship.
