neglected too long

I am in a situation. My spouse has his own business. he job is very demanding. he's a computer tech and is always incredibly busy. I didn't know it was going to affect our relationship so much. My needs are not being met as far as emotional, conversational, physical connection. We have very different backgrounds and i think that might be hurting us but i'm not exactly sure. There is hardly any emotion when we kiss and nothing much in the bedroom. when i have time off he'd rather play soccer or work on his business. I feel so neglected. what should i do. i want to leave??
