I am over 50 (has NOT been a problem in my dating life - and surprisingly, all but one of the men I have dated have been younger than me. The current one is 49, 8 years younger than me, and that seems to be just about the right spread).
I'm overweight (although not obese; BMI 28, I'd like to lose 20 lbs for sure). Again, surprisingly, the men I've dated have had nothing but good things to say about my figure.
I'm just saying - don't ASSume there's not men out there interested in you. You're smart, evolved (we all are after going through this process!) and debt-free except for your mortgage - you've got a lot going for you!
