I read your post and thought I would let you know that when I was 39 I met and started dating a 21 year old. Long story short,my family wasn't too happy about the idea. But,we both knew we were crazy about each other and we weren't going to let this affect us. Although after 3 years together,we did break up, but he and I still talk and are very good friends.He still talks about getting back together. My family still asks about him. My point is,if I gave in,I would of missed out on something great. Two of my aunts married men 20 years younger than themselves and are still together!
I still prefer younger and know men my age just don't do it for me for a whole bunch of reasons. Stay true to yourself. You are happy when you live the life you were born to live. Get out there,have fun and have confidence it will all work out. BTW,my family now expects a younger man to be in my life. It's now a no brainer. Good luck to you.
