Ask About His Daily Schedule
The daily schedule could help you figure out whether the guy is emotionally available. If he spends much time in hanging out with you or other friends, there is a big chance that he is single. Or you can simply ask about weekend plans, which is even less suspicious. It is a bit tricky because guys might answer your questions vaguely and you can’t know it for sure. But if you are lucky enough, you may end up with more information in your hands than you had expected.
See If He Flirts
Normally single guys flirt while coupled ones don’t, so you can simply observe how he reacts to women around. There are rare occasions that some men don’t know how to flirt or those who already have someone keep on flirting around. Checking if your crush flirts with other girls could give you clues of his relationship status.
Ask His Friends
Asking his friends may be the closest to directly asking him, but it works better after you got introduced to his friends. Humans love to chat about friends’ relationships, so it’s common and understandable that you are curious about rumors or gossips about him. Just remember, you need to be subtle while asking, or else the talk will turn to that why you are interested. And then you will be the main topic of conversation, which is not what you want.
Beat Around The Bush
If you don’t mean to play it straight and leave things as they were, you may approach someone at the seat and say: “Is this seat taken?” The key point is to step one foot in his personal space either accidentally or intentionally, and be prepared to withdraw if things are not looking good.
Strike up the conversation and keep it casual and general, because you don’t want to make the person you’re curious about panic and even run away. Normally you can beat around the bush by telling mixed stories of your friends.
