I think it`s wonderful news too.
The distance may draw you closer. For several years my husband worked about 6 months a year in Alberta (oil) while I lived in Ontario, and our visits when we had time off were fun and refreshing and it gave us each space as well, to just do things we like to do when we were apart.
You can talk on the phone several times a day and it won`t seem like he is gone and if this is all leading to retirement, it`s got to be well worth the effort.
