This is my take situation i am and have been happily married for 37 years so far. If I outlive my husband, there is no way on this earth, at this stage of life, that I would want to share my life and home with another person. I would certainly be open to making new friends ,but that is it. Surely, I am the manager of my life, if I make it clear, only friendship, they will get the message. A friend of mine, who in her 30's, ,was left by her husband, has been looking for years ,to find her Mr. Right. She is now in her sixties, got married to Mr. Right, last year, after searching for 30 years! If that same situation had happened to me, I too would have searched for my soul mate. I would never ever want a second Mr.Right. All I need is good friends, my children, doggies to fullfill my life, if i am widowed. Sorry for ranting, but i have given this lots of thought. We are all different, and have different needs, there is certainly no right or wrong, on this subject.
