ah, ok... so you were working under the belief that she also wanted to work on the R...

except...

you continued to get mixed messages and from how you've stated your perspective, she never really moved towards you to reconnect... aside from the passive action of initially sleeping in the same bed...

so it seems like really, she assumed that her mind would just change, without having to make any effort...

cake-eating for four years under the guise of "working things out"...

oh well, live and learn I guess... I can understand the half hearted attempts and gestures by you... and she can once again leave the M and happily tell anyone who would listen that she "gave it one last shot"...

OK, so I don't think you can live in "could'a / should'a" land...

Can you list some key complaints she might have and what kind of 180s can you do around those...

And also, what about GAL...?

And remember, no matter what, do this for you and make the good stuff stick... she NEEDS to see the positive changes in you and trust that they are real and she will probably have to get some "mystery" from you to draw her closer... to become curious about you...

That's just my take on things... certainly not a (or the only) path for you to take... do what feels right for you and do what works...
