Been through similar experience (divorce early 40s), and it's a mixed bag as always. I entered the dating game thinking it was going to be futile. But I was tall, good head of hair, relatively handsome with a good career/lifestyle, well put together, confident, an assured talker and presented as kind. I never knew most of that until I realised I was making an impression on a wide variety of dates. It was a relief.
I dated for about three years in total. A lot of first dates, some one nighters (not my fav), and then anything from 2-5 dates to couple of week/month relationships.
I dated approx 15 years younger through 5 years older, I quickly found that most 10+ years younger were not good long term prospects (for me).
With the women I dated that were much younger, I found that most would state that they prefer the maturity. And while I don't think they were necessarily looking for a free ride, there was definitely many cases of lack of financial independence and/or esteem. It's not wrong, but it wasn't for me.
I ended up meeting my amazing DP who is about 7 years younger, totally independent, ambitious and makes me laugh everyday, which is perfect.
