Good advice.
The unknown is often tempting and easily overvalued, while the known (partner, relationship) often feels boring or stale.
> "I don’t regret my decision to be with my current partner as he has given me two more beautiful children"
If that's the best (and only) thing she has to say about the man she has been with for years, it's no wonder she's yearning for someone else. :-/
Some women complain that some men are only wanting them for sex. The instance where the woman wants a man mainly (or only) to have children is instead seldom mentioned; alas, maybe this is such a case.
