I thought this was the plan
described in your other post:
We've come up with a strategy: we're going to give it a couple weeks of consistent behaviour (they meet whenever and make out but nothing beyond - I accomodate as best I can) and then I'll likely head out to my parents for a couple or three days to give her the space to think about what it is she wants.
... it will all hinge on her ability to maintain a line out of respect for us and what we're trying to heal. If she can't, then I guess I have my answer.
If you are trying to figure out how YOU are to behave during those few weeks?
I think you could be "plain roomies" during that time. No sex, no making out, no kissing, nothing like that. You are not obligated to spend time together or be her fallback person to hang out with -- have a life of your own, go out with your own friends. Could share the food, bills, chores as any "regular" roomie would. But keep it "platonic roomie" while she figures herself out.
Don't fall into any "romantic partner" behavior. What I'm saying is... could not bother with "secondary romantic live in partner" stuff if that is too confusing a role right now.
Could become willing to step back further than that so your behavior/role is clearer to you and you can better hold yourself apart from the wacky that's been going on. Be "roomie only" for a few weeks. Be willing to do only your self care at this time. You in charge of you and your choices. Let her be her in charge of her and her choices. She will demonstrate if she can abide by the agreement and be respectful of you or not.
If the home allows you to have your own bedroom space or at least your own bed, could move the furniture around to accommodate for that. After X weeks of giving her space to figure herself out... if she's not actually doing that work or if she's basically keeping you around just to help pay her bills?
You have your answer. She's not into you like you are into her.
And then you may have to think about moving out to your own space and ending this relationship. You don't sound especially happy in it.
