Basements are nice and quiet for sleeping....
drew what is keeping you from moving back knowing that you will be benefitting your kids (biological and others?)? It should be easier for you knowing that you will have a voice recorder going 24-7 around her so that excuse or reason is eliminated. Have you read through the threads and seen the chaos and monetary hell you are facing, let alone not being there for the kiddos? I am a newbie here but I can tell you that it may seem rough at first; but get back in the house and play the long game at the very least for the kids. The folks on this forum will help you through every battle step by step if you are willing to take the advice.
Keep your head up and get back in there (your house) as there is a war to fight!
I might also add that you should start your own thread and one day soon hopefully you will be posting to new guys here how you got back in the game and hopefully kept the house, and didn't loose out on any more time with the kiddos!
