I think there's no chance she'd move into an apartment if I were going to stay with the kids 100% of the time. She might be tempted on some level (the level that is screaming at her to live what she sees as a more exciting life), because she'd have so much less in the way of parenting obligations and more time for fun, but I think she'd think society, friends, family, etc. would judge her (and I agree they would). So, I think she'll push for the apt but, if I say no, will then just move to a stand-alone 3BDR. In both sitches, I'd lose 50% time with the kids, but the latter is much more expensive.
Honestly, I think I'd file now if I could get the son-needs-the-school-zone thing sorted. It might be that all he has to do is be in the zone when school starts next year, which would be early August here. I need to look into that, but it might be my end date I could be pointing to if I do end up doing the apt thing.
