How can I find out if the friend I like is single?

He never mentions or talks about his status.
We haven't seen each other for a while because we're both busy with work. I already checked his social media accounts but I found nothing coz he rarely posts anything. I thought about asking him directly but I don't want him to think I'm being weird. What should I do?
