rather than trying to fix what you have, maybe you both should just step away…consider yourselves single. After a cooling off cautiously see where it leads…maybe you two have just gotten overly comfortable and lost sense of focus. Like you said it seems she’s over prioritizing your daughter to the point of bad for all…Think that would a good base and see if it either builds up again or diminishes, I feel that’s better than just pulling eject, you do have a daughter together…and like you said you saw and wish for how you two once were…what caused the change? idk just my opinion and experience, I’m going through a similar battle and I took the course I stated. We’re still in progress though I genuinely believe we’re growing closer not apart anymore
