Separating physically without abandonment

I understand the logic in signing an SA prior to physically leaving the home, but what if you just can’t stand living there anymore-- is it acceptable (assuming one can afford it) to move out and continue to pay all obligations (mortgage, food, etc.) and not be considerd abandoning spouse, then later work on an SA (or litigate)? Is abandonment strictly an economic concept, or does it apply to emotional, sexual, or other non-economic aspects of marriage?


As I have said before, a claim of abandonment, while encompassing more than economic factors, does not carry much weight in court these days, and many spouses leave the home prior to having an agreement which out affect, especially if the monthly bills for the dependent spouse are taken care of.
