I didn’t catch the live but since when did she care about Harper? Her problem is she’s still in love with her ex and wether she wants to admit it or not, she was hurt so badly by the relationship ending that she’s scared to fall for someone else and end up hurt again. She doesn’t want to be alone and shes not happy alone, if she was she wouldn’t have moved a man in almost immediately after her split from her ex. She definitely sits on dating apps talking to men. She’s a very lonely woman and it’s clear to see.
