Hard to say. But I've been thinking about this, too...
My mom died almost 2 years back, and my dad was utterly devastated for over a year. But he is a very social guy! He enjoys being with people, and marriage is good for him. He loves dancing, music, traveling, dining out... Solitude makes him depressed.
He joined eHarmony back in September, and I just got an email that he believes he has found a really special lady who lives not too far from me. Really a gem, from what I've been learning. We (my siblings and I) think she's a perfect match for him, if all works out. A wife is just what he needs. And he's a great catch for her, too.
So, as for me... I guess a lot will depend upon how lonely or social I feel after I spend about 12 years mourning my husband (now been married 20 yrs.)
