Forget it. There is nothing wrong with the age difference — they’re both legal adults and older women date younger men the same way older men have dated younger women for ages. As far as loyalty after one date 😯 it’s not warranted. It’s entirely fair to play the field until there’s some kind of commitment between two people, which she could hardly expect from you (or you from her) after only one date.
If you like her, continue to see her, and if you want a commitment from her, let her know! 😉
I hope that helps — and that you’ll join me on Facebook. Here’s the link: [url][/url].
