I am not looking to get out of CS by any means. But if she (currently) is not looking to take half of my 401k and doesnt even know about alimony/maintenance then so be it. This might be an (easier) route to make that happen and keep her happy as well?

I obviously want what is best for my kids and will be providing CS for when they are with her 50 percent of the time, but the numbers I got from one of my L consults was like 3k a month. That seem excessive to me. We don't spend anywhere near that much on the kids per month at this point in their lives.

Is this a fairly common number when one person makes 3x more than the other spouse?
