Congratulations for your new house. When are you free so I can pop round for a drink and bring you some home made cakes? :-).
I understand how you feel about SS as it's a reminder of your XH, on the other hand you have been part of his life for 13 years so I think it'd be hard for him not to be in touch with you. I'm still in touch with SD (not regularly, but still here as I was introduced to her very early on in my relationship with her dad).
I admire you for all your accomplishments and I know in no time your garden will take shape!
As for NG, I don't have any advice just enjoy his texts and company when you see him. No expectations😀.
