If that is what you decide to do it can be a good thing if you use it (the separation) wisely. I now you have been recommended a lot of books to read and I and recommended a few to you myself. But, if you do separate pick up a copy of "Getting Back Together" 'how to reconcile with your partner-and make it last' by Bettie Youngs Ph,D. and Masa Goetz Ph,D.. It has brought so much sanity, hope and understanding to me about my own separation. It also teaches you have to use your separation wisely and lays out a good path to reconcile and what to do if you do reconcile.
And remember that whatever you decide to do, we (the members of this forum) are here for you.
