I agree with the others. This is not controlling. This is protecting. Plus she said she had done so already. Did she lie or is there a miscommunication?
I understand your reaction and probably would react similarly if in the same position but is your reaction proportional to the "offence"? I think it is inappropriate and untasteful on his behalf, but I am not sure it merits taking out the baseball ...
Ok, I talked to her about it, and she did unfollow him, and she showed me on her phone that she isn't following him, so I'm not sure why when I look her up on my acct it shows her following him. Anyway, I never use Instagram and she doesn't really use it much, so she said she didn't know she could block him, she tried to stop him from following her but couldn't find a way to do it. She said she would find out how to block him and do it.
As for the baseball bat, probably a bit over zealous, but it would feel good right about now. It sure upset me a whole lot more when I saw him like a picture with my son than when I saw he liked a pic of my W... I told her that I understand she can't control OM actions, but I will take action if needed to keep him away from my S.
