I'm gonna throw out something that I don't think has been mentioned before...the big "M", and I ain't talkin' about marriage either. I began seeing my ex-g/f when she was 47 and I was a youngin' (39). We had a great relationship for about 4-5 years, but by the time we broke up after almost 9 years, I didn't even recognize her as the same person anymore. I realize it doesn't affect everyone the same way, but when they call it "the change of life"...well, there's a reason
. That being said, go for it...with eyes wide open...good luck!!!
ps: When we broke up (her decision), I was still basically the same guy I'd always been...her, not so much. Still no regrets however....
