I usually end up dating guys that are several years younger than I am, but there's not that much difference between a single 45 y/o woman and a 35 y/o male in the social situations .... between 29 and 19 .... that's a huge social situation difference .... so ... good luck in finding what you are looking for, but I think anything more than about 5 years older than you and the woman is probably not looking for someone in your situation. Just my opinion.
