Alright guys. Advice, pls. I'm middle-aged, and just breaking things off with my now-former fiancee. I won't bore you with the details there.

I'm middle-aged and overweight, and I've played the beta provider for long enough. What's my route to improvement?

I'm mostly not interested in the whole alpha male thing. And I'm (at best) mildly interested in meeting, let alone sleeping with, women. So what's my best course to better myself?
