DEAR ABBY: I recently started a romantic relationship with “Doug,” a guy I have been chasing for a while. My friend “Cassie” helped to set us up, and I am grateful. Doug and I talk every night and are very close.

Cassie has a reputation for being a flirt, but I didn’t think much of it. As the months have progressed, I notice her talking to my boyfriend more often. I’m OK with her being friendly, but when she hugs him or tries to always sit next to him, it makes me uncomfortable. I’m scared she’s trying to come between us. Recently she told me that she thinks he’s cute.
