I did it once, on my first play through in like 2012. As I recall, everything about it is super awkward, and combined with the robotic NPC animations, it just made me feel embarrassed to be going through with it lol.

Then it felt like every other line from her had "my husband" shoved in. It got really annoying before too long.

Also never adopted a child in the game because Bethesda's child NPCs are always dog shit (IMO). Actually the ones in Fallout 3 had an interesting thing going on with their commune, but they are still insufferable.
