Hi! Seeking someone to remind me of title of thriller book. It’s older (at least 5 years). Plot: young friends told from women’s pov she and boy date. She doesn’t have any friends. He’s popular & attractive. Later in life he marries & the old friends rekindle. She thinks he wants to be more than friends & kills new wife. Very good book, would love to read again as I don’t have many details. Help appreciated. #thriller
