1 year no sex

Is it still normal for married couple to not have sex? For past 3 years I (wife) am the one who initiates (32F), and when we do it, it feels more of a task than love. So from last year I stopped asking for s3x, and he (37M) has never asked for one, i know he doesny cheat on me that is for sure, but how can he be like this? Now, thinking about having sex with him, i feel strange about it. I feel i cannot do it with him anymore.

tl;dr tips on how we get back intimate together
