Making extended eye contact with you, where he's so into you, he will not move his eyes off you.
You can tell by if he always stares at you, or messes with you. If he talks to you, don't panic just be yourself and it will all go smooth
Can you tell if other guys are flirting with you? Nick's a guy, so I'm sure it wouldn't be much different than a lot of other guy's ways of flirting.
You can tell if he's flirting with his ex, and texting/messaging her. If he talks about he sometimes as well.
He'd say it
he could b flirting if he wrote alot of compliments to u
Many show off as a form of flirting. If a guy does things in order to get your attention, he is doing both.
You say "I miss you, even if I was ignoring your flirting for awhile."
Make eye contact and then when he talks to you tell him.
Catch him while he talks in his sleep :-)
He looks at you, touches you, or talks to you or about you.
If the guy is flirting with you through text, then he may like you.
Just start flirting with him. Make yourself noticable
