It seems like she's trying to get close to him as much as possible while keeping him all to herself and reveling in his moderate suffering.Still trying to figure out the end goal.
Earlier, she had him meet "another girl" (it's just her in disguise) and have the fictitious girl stand him up and ghost him. Then afterwards, she presented herself yet again as the oasis in his dried up love life, even if that oasis might just be another mirage too. I'd say she has him emotionally isolated now already.but we haven't seen any actions that would actually isolate him or prevent escape.
