Assuming you took XH's surname when you married (I know lots don't) did you revert to your maiden name when you split?
I took STBX's surname when we married, it's the DC's surname, I don't want my maiden name back (belonged to my abusive father), but I don't know if I want want to keep STBX's name - changing it seems like a bit of a faff and I think I'd like to have the same surname as the DC. But is it odd to keep an ex-husband's surname?
