my wife left, but still lives with me #3/continued

[tough spot]

So I got a letter from her lawyer today. I have a hearing on May 6th for 'temporary custody, child support, and parenting time'. This is a shocker. We had discussed coming up with a temporary custodial agreement ourselves, getting it ratified by the courts, and proceeding on with the divorce.

the intent was to allow us to leave the house without the risk of 'abandoning the home' and hence potentially affecting long term custodial agreements. Now I have to go to court? I am going to have to talk to her about this tonight/tomorrow and ask why the change.

This has me highly concerned (understatement big time). I just can't figure out how a parent can think it is best for the children/right/fair to not split custody equally. There are no anger issues here, there is no drug abuse here, she knows/admits/has stated that I am a good father.

She must think they are better off with her? But why? I do not know and this is putting me really close to freaking out.
