This is such a subjective topic and I agree with what wannabe has said.
That doesn't mean that I don't have sympathy with nonono either, but however close you are to someone else, it's impossible to actually fully understand how they are grieving. I'd also suggest that the grief you feel for a partner is different to that you feel for a parent ..... not somehow more "worthy", just different, and I can imagine this is how upsets like this arise, because the 2 parties concerned (parent and child) are both grieving for the deceased in different ways, because to each of them, the woman in question played a different role.
I hope I haven't offended in saying that, was certainly not my intention ...
Whenever I read stories like this, I also wonder about the vagueries (sp?) of fate which lead to anyone ever meeting anyone else, and what "it" is that means we are attracted to them ? What I'm saying is that a recent widow(er) may have absolutely no plans whatsoever to deliberately seek out a new partner, but then one day they meet someone, the chemistry's there and they just "click". Okay ........ so, in theory, they can walk away, but why should they if this chance meeting has bought a little glimmer of hope and happiness into a life which has been utterly miserable for the last few months ?
Should the recently (and again, that is subjective - everyone has a different defintion of "recent") bereaved turn down opportunities of finding love again, because, other people believe it to be "too soon" ? After all, if they wait until other family members "allow" them to start another relationship, the moment may have passed. What I'm saying is, you can never tell when love is going to strike.
