She's going to teeter back and forth. When she does that stuff, sometimes it's temp checking. If it happens after you've been especially aloof, that is almost always what it is. She's trying to feel you out.
When she talks about a fitness franchise, what she's really asking is "would you want to be around me for that?" if she knows the answer is "yes," she knows she's safe and can table you for later.
Guaranteed, if you engage in those convos and seem interested, she'll run the other way.
So until she proves to you she's interested in an R by directly stating it, agreeing to full transparency, and starts demonstrating with real action that she is remorseful and that a new R is what she wants (who would want to go back to the old one?), all of that is just temp-checking fluff.
Don't let her lure you into a false sense of security. You keep doing what you're doing (seems like its working) and when/if she's ready, she'll sit down and open up the R discussions.
In fact, next time she starts bringing up all this spending time together, I'd really try to squeeze her on it. Never just jump to doing those things; make her work for your time.
Say something like "I've already made plans with someone that day, how about x?" It will show her that you are your top priority.
or when she talks about future plans, that's a perfect time for a truth dart.
like I said before, it might really hurt to do that because you're not fully detached, but you need to fake it 'till you make it.
