My (M23) GF(F28) has photos of her ex BF in her phone and drive. She is also in touch with him via instagram and whatsapp.

When I asked her why she is in contact and has photos of him/them, she said she likes to keep pieces of her past. She said that she doesn't feel anything for him anymore nor she sees them.

This is unsettling for me for a few reasons. She uses his laptop. (Her laptop broke down so she is using his as her main device). Apart from that, he texts her trying to talk to her, and she has kept him in archive on whatsapp. She says he keeps annoying her. When I ask her to block him if it is bothering her so much, she refuses. Whenever she shows me something in her gallery, that guy pops up everywhere. She has more photos of him than us.

I deleted all texts and media with my ex and I am not in contact with her. I told her this and she said that she has normalised talking to her exes and I should do the same.

PS: She is connected with her BF before this ex, as well, and he keeps calling her asking her to meet him, and he asks her of her location as well. He called once when we were together and the whole call was like he was trying to get her to meet him. My GF said he is annoying as well but refused to block him when I suggested.

TL;DR: AITAH for asking my GF to delete her media and her connection with her ex? Either ways what should I do?
