Parents are splitting up after 26 years together?

My husbands parents split recently after 35 years together.,..similar cirstances...the only advice I can give you is not to get involved...dont listen to any sniping or bitching...don;t advise either of them on any moves they make...or choices they have to take...they are adults and so are you...your relationship with both of them can only improve with this happening....if either of them begins to involve you you should say that you aren;t happy discussing their relationship.
