STBX has been the “mother” of MY dog for the last 8 years. We are going through a divorce and i have official brought my dog to my new living situation.
When i took him, her demeanor was as if she didn’t really care. Now for the second week in a row she’s asked about him (dog).

Is it rude to just not reply ? or i’m i overthinking this?

Any feedback would be appreciated .
