Winds of Change

Today a rather blustery day here kept me from riding and instead got me thinking. Like the seasons outside it seems the winds of change are blowing through my life as well. I am after five or so years considering going back to a full time job again. That is other than the full time job of being a mom to two young boys and the restoring of a 135 year old farmhouse and the ten acres that go along with it. I am wondering how I will fit all my chores and my passion of riding in with working a 40 hour work week. I am also considering sending my aged gelding Tank, to a retirement home or as a pasture mate for another family. As I write that I can't imagine it, how selfish is it to send him to another family after 12+ with me. I am stretched in all ways it seems these days and I really would like for him to get more attention than I am giving him. I am struggling to come to a happy median with my allotted horse time and trying to make the best decision for all involved. Have any of you been faced with this predicament?
