I lived like roommates with H until I asked him to move out and figure out what he wanted to do. We shared meals together, spent all our evenings together, and went out together on the weekends. Even slept in the same bed, spooning. No sex for months. Ultimately it wasn't enough...mainly I believe on his part. I started GAL several months before I asked him to move out. He didn't. It became too depressing, and I didn't want to float along with no direction for US any more. I think living as roommates would only work long term if there were clear rules and boundaries that you both agreed upon 100%, but even that's no guarantee he or you for that matter would abide by them. It would be tough.
