If she turned around today and said she wanted to come back...I probably wouldn't say yes.
Imo, you are on the right track, because if she came home too soon, before she had done her own work, the odds of her leaving again are very high. And the second leaving is harder than the first since everyone's (especially kid's) hopes are all up.
I am in my divorce's 20 day waiting period, and even if I still was standing, I wouldn't take stbxw back. She hasn't begun to do her work. And, the peace, stability and happiness in my house and with the kids has been amazing for all of us. The kids are doing awesomely (finally) in school, we laugh so much more, etc.
Ain't NO WAY I am going to muck that up.
This full time solo Dad gig suits me well, finally get to be the Dad I always wanted to be (one of those looking back and saying "what the heck took me so long, and why did I allow her to keep me from that?" things).
Keep going, and happy holidays!
