Nero -
I think that there is always the possibility of finding another true love. Generally, I agree with you, but I think that it has to do more with the fairy tale of "happily ever after". Increasingly, because of the stresses of modern life, that's becoming less and less likely. Or, in your case, because of tragic circumstances beyond your control.
I truly believe that in cases like yours, one has to hold on to a hope that there's
one more true love out there. You know what - there are
tons of single moms out there bouncing around, not particularly looking, but hoping that
maybe some day they'll find a sensitive, loving man with whom they can share their life and their kids. Maybe you're that man.

Don't give up!
