I don’t think anyone is that bothered by it, more commenting on a public forum that it’s an odd set up.
She has packed up her old life and moving on with this new man. Played the Merry Widow for a very long time, but this relationship has now started and escalated fairly quickly with the the house move new baby etc,
Quite disrespectful to that new life to cling on to the old one so much.
Doesn’t mean she has to forget him or not mention him, maybe give the father of her third daughter a nod in some way?
