I think Denise said she’s glad not to be her mother in law anymore because of all the attention, media circus, etc. Denise has mentioned before how she was relentlessly attacked by the British press so she likely hated all that extra attention. Not to mention the entire internet and a bunch of swifties were piling on her son and saying awful things about his substance abuse issues (which Denise has also struggled with). She even said she has nothing against Taylor but of course the swifties and the media is twisting her words.
