I told girlfriend to delete a guy "friend" of snapchat, was I being wrong?

My girlfriend is anserwing everyone while Im sitting next to her, except a guy she had slept with before me. I told her it was weird that she could open snaps from everyone except him infront of me.

I told her 3-4 times that it is weird but she still did it until I told her that I had enough, and she had to delete him.

Was I being too much?
