Is my boyfriend cheating on me
he keeps looking at my bf (best friend)
by looking no by his reactions and the way he treats and talks to her it could tell you if theres something goin on
No. He's simply looking at her. It has no significance whatsoever
that doesn't mean he is cheating on you!
Pay attention to how he's interacting and talking to her. If he's just looking at her and you think he's cheating...there might be some trust issues...
Talk to her about it but not in a mean way. For example, "do u think my boyfriend likes you?
