I am a widow. I was married to a lovely woman who was diagnosed with cancer (I proposed to her shortly after the diagnosis) and despite spending our entire four year marriage taking care of her and looking for a cure (everywhere from Los Angeles to San Francisco to Palo Alto to Houston Texas), it just wasn't there. She lost her battle with the disease but went down fighting to the very end.
If there is one thing I took away from my marriage it's that love is THE most amazing thing in the world. Most would say my marriage was probably really sad/depressing/difficult. And though it was all those things at one time or another, for the most part it was great. Love conquers all as the saying says! Life is short. If there is one thing I learned from everything I went through, it's that you need to enjoy every moment and not take ANYTHING for granted.
And for any of you women who are worried that I would ever try and compare you to my wife who passed away, that will NEVER happen. I have spoken with many widows who found love again and if there is one constant among them it's that when you find love again as a widow the new person loves you in a new way, a way totally different from the other person you lost.
