By his behaviour
He his the way he is, you can't force him to change his personality. Maybe he's not that kind of guy. However, if you subtly show a little bit interest in him, he'll hopefully figure it out and will be more confident to be forward with you.
Coulds jusy mean he is just shy.
if they loose interest in you
Flirting is way for people to get noticed. If they like a guy they will flirt with him until he shows interest in them.
The most obvious way to know if a guy likes you is if he shows genuine interest in your life, makes an effort to spend time with you, compliments you, and tries to make you happy. His body language, such as maintaining eye contact, leaning in when you talk, and mirroring your actions, can also indicate his interest.
youre too young... awk By shanice: You are not to young. Just be yourself and let the guy know that you like him by talking to him or seeing if he likes you back. Talk about sports or mma fighting or TV shows or things that you know will interest him.
it seems like you (or the person) he showed interest in wasnt showing they were as intersted as he was so he decided to let it go
When he tells you he loves you and shows it. Don't believe them all...
In truth, you can never know. You can only accept what he tells you combined with what he shows you.
Ask him but don't seem harsh. but he might be bisexual.
well the most obvious way to tell a guy isn't into you is by him ignoring you. if he shows no interest when hes around you then that's a dead give away. also if he is making up excuses to why he "cant hangout" then that's a sign that he is avoiding you. move on and find a guy that likes you for you ( :
He has an interest in you and hopes you like him back.
