Hi, I had this situation with my ex husband, after our marriage broke down we had to live together for almost 3 months until alternative arrangements had been made. Prior to this I would have assumed it wouldn't have been that difficult, after all, we had lived together for over 20 years. The reality is, it was an absolute disaster! My husband, who I had loved dearly, had gone and in his place was a man I didn't know from Adam. I know I tried desperately to make it work and, to be fair, I'm sure he did but we were no longer a couple, just 2 people stuck under the same roof. The only advice I can offer is to try and keep yourself busy, the less time you spend at the house the better. Move yourself into the spare room. I put my husband in the spare but he seemed put out that I had the larger room. It doesn't matter so go yourself. If you have family or friends that you can spend time with make the most of the opportunity. I wish you the very best of look, it will probably be a bumpy ride but the end is in sight xx
