crossing the line???

Hey ladies! So right now I'm a little annoying by the way this one "girl friend" of my SO has been commenting on his social media. He has limited so many things for me and I been trying to keep it cool but I feel like it's too much already. Not only does she need to comment on almost everything but every comment she writes has a winky face. She lives in Mexico and that I know she would never comment or anything until after he went to Mexico a few months ago. I know this probably sounds childish but I'm very annoyed. What would you ladies consider crossing the line for a friend??
