LR doesn't mean no contact and no communication at all. I talked to a DB counselor, and I have to maintain some communication with my spouse because of the kids and finances.
Cutting off all communication would be seen as passive/agressive as PDT says above. Just keep it to necessary things and don't be seen as pursuing/begging/etc. It's about making them wonder what you are doing - also, it involves GAL'ing (LR is not just being silent) - and helping them see that this is not getting you down or ruining your life.
