Ya it’s time please choose one man. You are hurting both. More so Kian who just wanted to change for Tinsley. After confessing everything she must have informed Kian before going to bamford house. This is just so unacceptable. She is really being selfish here.
I think what she feels is a sense of obligation towards Ross, she feels she owes him something.
She thinks that he is the one that saved her. He has never told her the truth.
