I do agree you should give it some time, but I'm also concerned at the mother-idolatry he seems to be showing. Yes he may come around but I'm not about to write off your concerns as nothing either.

I understand grieving and I understand how it takes a long time to get over one of your parent's death. I'm not brushing this off.. I am however, concerned about how much he truly does paint her as a saint, or even a goddess. I mean really? She sounds like he is making her out to have done no wrong, is angelic in beauty... I'm sorry but I reserve such devotion for my wife, gf or significant other, not MY MOTHER. He almost sounds like he worships her, and is in love with her over you.

That he wants to name the child after her isn't out of the ordinary but that he states how he knows the child will be beautiful, like her, as opposed to you, the mother and his wife, is, quite frankly, weird.

Even kissing a pin with her picture is pretty much showing idolization of her image and borders on worship. Especially after a year, even if one is still grieving after a year, it should have somewhat calmed down by now.

Give it time but honestly, keep your eye on this. I can understand your feeling put off by this, it's very justified.
