I totally hear you and what others have said about the nesting. It is a struggle and I am not sure how I'm going to handle it. Right now I'm at the studio and have been all week and the problem I have is I ENJOY being here. It gives me the space I need to do my own thing and not be interrupted 100x a day. I love my kids and I love doing things with them, but with Covid and working from home while they are going to school from home, it makes for a stressful situation where I don't feel like I have the time or space to work on me. While I'm here I can blow off steam, take a break, read a book for 2 hours without being interrupted. So as much as I hate it when she's here (knowing what you've all said) I also don't want to give up my time here.
Well if she gets her own apartment full-time, you would get all of that alone time at home instead of the studio. So don't look at it as losing your alone time, just moving it back to the house.
But I would have the kids which would make it difficult to have alone time. We've got a 9-month lease on the studio and it can't fit 4 people if she was to have the kids. We're also trying our best to keep a semblance of normalcy for the kids. For the most part they've been stuck in the house for 9 months now because of Covid which has rocked their world. It might be better to just rip the band-aid off, but we're not there yet with the kids.
