What is your co-parental schedule like ? Who is "in charge" of your child for the coming five days?
The recipe is quite simple, because I am going to advice you to do the exact same thing in both cases.
Case 1: According to the schedule it is your time with your kid: You get out and do something fun with your kid - go to the beach and build a sandcastle, go to the forest and look for trolls and goblins, or find a hidden treasure. Go to the library, go visit family or set up playdates. <--- Go OUT and live life and get some great experiences with your kid.
Case 2: Your STBXW has your kid according to your schedule: Well... GO OUT... Play golf, visit friends, visit family, hit the gym, go for a long walk, go to a concert, go to the cinema....
Will you want to? most likely not.. You want to stay at home, so you can use these 5 days wisely, and logic tells you that wisely is to be there for your wife, so she can see that you are really trying, and that you are a good husband.... its pursuit, and wont work. Let her fly.
In case you missed my 2x4.... GET THE HECK OUT OF THAT HOUSE, it is sucking you dry, and you need to get up and get out, no matter how tired you are / not feeling like going out...
These 5 last days are meaningless in the bigger picture.... Do not think anything will change between you, because thats on a whole other time scale.....
