Forgive me Reality & co, but you seem to be being a little harsh. Gemz has (now) acknowledged that the child, should it be her DHs, would be entitled to have a relationship with him (not her choice, as we all agree.)
But I honestly can't see she has moral obligation to have a parental relationship herself too - she's not a parent to the child. Socially, biologically, whatever.
It would, of course, be nice if Gemz offered support and kindness, however.
The trouble is, Reality, that when you avoid creating an off-the-shelf family with 'traditional' relationships, you have to accept that your new structure can't suddenly call on other people who aren't involved to support it. You don't have priveleges to rope in kindly strangers - it's not their problem, however much you try it on - or use the 'kiddy' clincher argument.
Anyway, to be quite honest, surely the baby would be way better off having friends/relations who actually wanted to see them - can't see anybody benefiting from such a grudging relationship.
