I think it depends on the petson saying it. A parent, caregiver, or close friend using distancing language is A HUGE RED FLAG. In those situations, they are attempting to minimize their guilt by placing distance between themselves and their child.
For a bf since December, who at most knew the baby for a month or so, there wouldn't be the internal need to avoid the use of her name and endearments.
I think what we are seeing here is a guy who never met Evelyn, and has a negative view on having babies/children. He probably openly (and vehemently) doesn't want to father children, given his language in the interview.
