Missing him

I am in a casual relationship with a guy. This involves us occasionally meeting and having sex. After we finish our first round of sex, he stays on his phone for the rest of the time; he shows more interest in cricket and in the latest bollywood film. Last time when we met, he showed me pictures of his nephew on his phone.

When we are not meeting, he doesn’t really talk on text messages and does not call at all. I do not message or call him that often as I don’t want to be irritating. He hasn’t even taken me out on a proper date.

If we always maintain this distance then how can we be more close and develop better understanding?
