No sex? 👎

So the past few weeks my husband hasn't kissed me, hugged me, nothing. Hes not mean to me but he hasn't been affectionate at all. I've been trying to initiate sex for 4 days now and every time I get turned down. My feelings are hurt amd im starting to feel like he doesnt find me attractive anymore. I feel super unwanted. Ive said something to him and he just ignores me. What should i do? When he wants sex i drop my panties..
