Am i over reacting? (read details)
OK so I'm 14 and my girlfriend is 13. So i'm on Facebook and i see that my gf posted something saying (not using exact names for privacy reasons) "Bla-bla and bla-bla are weird O.o" and in the comments some guy i've never heard off wrote "They are weird but i love you haha" I'm really angry at the guy and feel like telling him "Back off she's mine" am i over reacting? What should I do?
