The old adage that "Love is blind" has earned itself blue ribbons in every decade of societal courtship. When emotions are allowed to stampede and trample the common sense of an otherwise sensible person, the result can leave one helpless. Often, we don't see things that should have been obvious to us from the very start. I have been there, and paid the price.
I am more cautious these days, and I try to remove the "love goggles" from time to time so I can make sure I'm not just seeing what I want to see. It can be hard to be objective when the perfume of love has you intoxicated. Fortunately for us seniors, we have a bit of experience under our belt, assuming we have done an autopsy on past failed relationships. Plus it has given us more time to get to know ourselves much better, and what we really want and value in life. I have admonished my heart (Emotions) to be sure and check with my head more often. We'll see if it actually works.
