Sent friend requests secretly to my close friends

We have been in different cities for eight months, and to be honest, a long-distance relationship is already hard, but something weirder happened yesterday. She sent requests to my two closest girlfriends, one didn’t accept, and the other sent me a screenshot, that’s how I found out. When I asked her about it, she said, “I wanted to see who is in your life or not, it wasn’t out of bad intentions,” but when I asked why she was checking on who I follow, she started talking about privacy issues. I want to react strongly, but we were planning to move in together, and I can’t figure out if I’m staying quiet because I don’t want this relationship to end.
