Who says they are
afraid and
can't commit? Maybe they just don't feel like doing it.
I can remember that at age 18, I would
never have wanted a guy who has his goals in life set out, a career, a steady place to live and a newer car, and who's looking for a wife. What I wanted was: discover new things and try them out, see the world, have adventures, migrate every year... Certainly not find a husband and settle down.
If those older women are what you're looking for, why don't you choose one of them? Are ten years of age difference such a catastrophe?
Btw, older women can be naughty too
