Hi Steve,
I only very recently registered and have read your thread. My thought is drop the online dating and try meetup.com instead. It is not an online dating site, but people create groups in areas of their interest. Find at least one meetup that interests you and then go to the meetings. You will make new friends with shared interests and get to do something you enjoy. It will greatly increase your chances of meeting someone. It is better than online dating because you already have at least one shared interest and more importantly you meet in person. That is what I learned after being divorced in my early 40’s.
