does it matter if I leave our home(move out) before anyone of us have filed for divorce

if you move out of your home, it may be very difficult for you to come back if you change your mind. If you have children, you should consider having a written custody agreement that could be submitted to the court for approval regarding their placement, prior to moving out. If you live in an apartment and signed or co-signed a written lease, you are not relieved of the financial obligations simply by moving out; same for if you own your home and have a mortgage: you can be held responsible financially if any of the mortgage payments are missed. While you are certainly not a prisoner in your own home, you need to weigh your financial obligations, the fact that once you move out that it may be difficult for you to get back in, and how your moving out may affect the placement of your children, if you and your spouse have children together, before making any decisions to vacate.
