My ex-husband and father of my children sadly died earlier this year. One of his friends, who I never met as she lives abroad, found me on Facebook messenger and has been messaging me a lot since he died. I feel for her wanting to stay in touch with the kids, and grieving, so I do reply regularly and the other day I sent her some photos of the kids on our recent holiday. Without asking me, she forwarded them to my ex mother-in-law who then said ‘I didn’t know you were going to X on hols: nice pics of the children that K forwarded me.’ I felt my privacy had been invaded somehow. I do make an effort to keep in touch with my ex’s family a lot, because of the kids, and I send them photos. But I object to my photos of the kids being forwarded without my knowledge/permission .Not sure if I can say something to my ex’s friend? AIBU?
