it could mean he is shy and love you
Another guy will express interest in you by talking to you, smiling at you, winking, perhaps stealing glances at you, etc. === ===
It does not necessarily mean anything - he may not be interested in your smiling.
By asking him.
he loves you
If a guy frequently glances at you, it could be a sign of interest. Look for other signals like prolonged eye contact, smiling, or making an effort to be near you to confirm if he likes you. It's best to observe his behavior over time to get a clearer picture of his feelings.
He might be imagining you making him a sandwich, its really difficult to guess based on that information
he glances at you constantly
he probably likes her and most likely he will think she's out of his league especially if the girl is pretty..
A shy guy at church who likes you may exhibit expressions such as smiling nervously, avoiding direct eye contact, blushing, or appearing flustered when interacting with you. He may also give subtle glances or steal quick looks in your direction.
try smiling or a small wave and see what happens if you get no response write him off as a creeper.
You will catch him/her taking glances at you!:)
Usually when you catch a guy looking at you and smiling it's because he might like you!! If he's a shy guy, then he might be too scared/nervous to talk to you and sticks to smiling and looking your way. If you have the courage go and talk to him!! :) if not, then you can make a friend introduce you guys! Good luck!
