I'm lost on doing LRT while she's still living in the house with me. She already feels like I don't want her in the house and she's working on moving out...but she wants the "old me" back.

So if she wants the "old me" which requires doing 180's from my current behavior and includes doing nice things for her, how do I do LRT? I get not saying ILY and not buying flowers, but does it just mean I act like I don't care if she leaves? Just keep being nice and helpful around the house and upbeat around her?
