For context, my exwife a little over a year ago started dating a twice divorced man from Pakistan where the marriages were arrainged and he lost custody of both daughters from his 1st marriage and kept his two sons from his second. His ex-wife # 1 straight up moved to Pakistan even though she was born in the US and her family remains.

About six months after, my ex wanted me to sign legal papers allowing her to get them passports. She lied about the intention of why and didn't come clean for a few months after I said no and provided information on who to get my 2 daughters State issued ID's. Turns out she and he wanted to travel to Pakistan with them to visit his two older girls.

So tonight my ex was a little inconsiderate and he was there when I went over to continue the tradition of reading Twas the Night Before Christmas and putting out cookies and carrots. Not thinking I took a picture of his license plates so I at least had some record of who he is since I don't know much. My ex-wife saw me and had me delete the picture. I did and then later apologized to both her and her boyfriend. I did again in email for a record.

Was I totally irrational and violating her boundaries or am I just doing some due diligence?
