...so he remains single all these times. He has shared with me that he has several female friends and co-workers that want to date him and he has given a couple of them a try but once they are in the dating mode, they've changed just like an unpredictable weather forecast so he has given up on finding a mate for a couple of decades now.
Now, he won't move passed friendship or co-workers status anymore due to the lessons he has learned over the years. He still hangs out with female friends and co-workers but as friends only. He said, being single has been pretty stress free in the last couple decades because he can still get just about everything a man wants but without the commitment and drama.
I told him that it's his life so if he's happy and content, continue!
Having a mate is not a requirement in life so one should do what makes one happy and live life to the fullest regardless IMO.
