Absolutely !!!!! Look forward. I promise, the best is yet to come. Not only was I married for over 30 years, I had dated him for four years before we got married. Becoming "just me" after all those years was an incredible adventure. ( although I freely admit it was a painful process taking those first steps ) My experiences led me to contact with so many women going through the same thing. The ones who did not thrive, were the ones who were so wrapped up in the past that they were unable to move ahead. I have no idea what your circumstances are of course, but my own motto became "the best revenge is to create a happy life for myself".
As Lewski709 said, there is a reason for everything. After several years on my own I met and married the most wonderful man. Who knew it could be so good? But I do not begrudge "lost" years. They made me what I am. And they make me truly appreciate each day. I'm going to shut up now because I am getting sappy.
