Married strangers

Sometimes I feel like my husband knows nothing about me and I know nothing about him. He doesn’t talk much about feelings or anything really unless it’s about work. I have severe on and off anxiety but when I say something about it to him, he doesn’t say anything or seem to care. I want his support but feel as if I never get it. I feel like I can’t go to him. I feel like we share a house and children but not much more. I want a connection but I’m not sure how to address the issues 💔
