And I agree with your friend.. unless you work on a golf course Polo's are not appropriate work attire even on "casual day".
In closing.. your whole point in this investigation to the validity of your marriage boils down to you needing to know if you can have another R after your W divorces you. If the marriage is valid then you may not have another R in the eyes of the church post divorce due to a sacramental marriage being binding for life in the eyes of the church. Now am I getting it?
