Need help please

Today Wife came over to pick up our D2 and came inside ended up staying for an hour we were talking fine having a laugh I was being friendly but only responding to conversation they she instigated. I thought it all went really well.

Two hours after she left my house she changed her name on Facebook deleting my surname. I know I really shouldn't care about this I just think it seems strange that she did it. Maybe she is trying to make me angry to create distance again? Or because I gave a strong impression that I was doing fine without her? I don't know it's hard to follow.

Any opinions welcomed.
