I realized recently that I have a habit of swiping left on guys who have “liked” me that I deem to be too good looking, too successful, too much younger than me (anyone with more than a six year age difference), too fit, etc…. If I am really honest with myself, I don’t do this because I think I won’t like them. I do this because I think they won’t like me…at least not longterm. So rather than open myself up to that kind of rejection, I just avoid it altogether.
Hmmmm. I'll admit that sometimes if it looks too good to be true - it isn't true. A model handsome guy with lots of money? Usually a Nigerian scammer.
Still - if you're just swiping left on people who are real just because you think you don't deserve them, you may be doing yourself a disservice. You have a lot to offer. (My best friend avoids the pretty guys too though because she's afraid they'll cheat. Not really my experience with the handsome guys I've dated since my divorce - they were no better nor worse in that regard than other men. )
As for the younger guys - it's an issue at your age. Not so much age but their stage of life. I mean, a guy who is ten years younger than you but has a ten year old kid - could be a great fit. A guy who is ten years younger, hasn't had kids and wants them in the future - not so much.
I did find that in my 50's the age differences didn't matter so much - although I did avoid guys with small children, only because I didn't want to revisit that phase of life. (One exception was Mr Big Lots, who still had one daughter in grade school, but she lived 90 minutes away and he only had her every other weekend so I didn't ever meet her in the short time we dated.)
