Going crazy

I'm going crazy. its been 3 months since me and my husband have had sex. and I'm starting to have dreams of me cheating on him. Though I never would. but its getting so bad to where I start crying. we have been married since April. I don't know what to do. we start making out and he seems like he's getting into it but then pushes me away. Masturbating doesnt do nothing for me now. And I'm to scared to talk to him. knowing he's probably gonna say I'm stupid or annoying.

What do I do?

This is us. He's 25 amd I'm 21.
