How do you know a boy is cheating on you!?
You can feel it in your heart. Follow your instinct
if they look at other girls or keeps checking his phone on your guys' dates
Ask him. This doesn't mean accuse him of cheating. Just say something like, I feel like we've been drifting and it feels like you might be cheating on me?
Hire a private detective
Ask around. If he is, someone knows something. Or check his phone.
they look on girls bobos and kiss them whan u are with your friends and ma-bey your Friend look at them
They are secretive more and tend to lie about the stupidest things.
