They apologized because they actually broke something. I'm not against apologizing for actual fuck ups. The OP's complaint wasn't that she didn't get support, her issued was resolved. Her problem with his "tone". If the husband had gotten upset and refused to help her all together that would be a much different situation that what was given. Other than "tone" HOW DID THE HUSBAND HURT THE OP?
@SMuser69 If someone doesn't hold the door open for me and they say, "Oops I didn't see you there" it's a mistake and I don't need an apology. If in the same situation I was actually hurt by the closing door, then yes an apology would be in order. Apologies are when your actions have negatively impacted a person. If you give them for anything they become insincere and I don't want my words diminished.
