The most obvious way to know if someone is married or in a relationship on facebook is to check their relationship status. If it doesn't say, you can always search through his public pictures to see if he's uploaded pictures of him and his lady or him at his wedding. Make sure you look at his ring finger to see if there's anything there. If there isn't any sign of him being married from those pictures, you can look at the pictures that he's been tagged in. That should be able to help you.

If a potential love interest does not reveal her marital status on Facebook, you have two options. 1. You can message the crush and ask directly about marital status. 2. You can make an assumption and “let the cards fall as they will.” It is inappropriate to continue to spy on a crush. Even though Facebook is a public venue, constantly spying on a potential crush is gross and unethical. Would you be happy to discover that someone was constantly spying on you?
