It’s over, now what?

So my (35M) Wife (34F) has told me that she no longer wants to be in a relationship but doesn’t want me to move out or get a divorce. I’m currently moving into our basement. We have 3 girls (7/5/3) and part of me wants to just go with this arrangement so I don’t loose them. At the same time it’s so hard to be here.

I feel like if I leave I loose everything, my house and all the work I’ve done here, my kids at least half the time if not more, the life I had been planning on for the last 8+ years.

I have a place to go (my dad’s) that my girls would have their own room at. Do I suck it up and stay for the kids and to make my “exish” wife’s life easier? Or do I leave and deal with the consequences of that?

I don’t know what kind of advice, thoughts, or comments people may have but I don’t have therapy until Friday and the only other person I have confided in just told me she’s out of the relationship.

Update:

I told her I’m not willing to stay in the basement, my oldest daughter has been asking for a sleepover with her sisters. We brought up the idea of them all moving in to the master bedroom while my wife and I each take a small bedroom.

This would be a temporary solution until my wife moves out (her decision and she wants me to try and keep the house, we’ll see what I can afford). We don’t yet have a timeline for when she moves.

We’re going to 50/50 common bills and split time being “responsible for the kids” (her words) so we can both start leading our own lives.

She’s turned down my repeated requests for couples counseling for the better part of a year.
