Kelleyg19, I'm so sorry you're going through this with your spouse. You must be under so much stress and heartache right now. Hugs to you.

I agree with Sandbox Sally, is the option of you staying in the home an option to you? But in terms of giving notice, I would say a month is plenty of time, especially if your contract only provides for the standard two weeks. It's considerate of you to think of your clients as well and try to minimize the impact on them, but you have to do what's best for you.
