So me and my GF had been dating for a year and half now and she joined a discord server and made some friends, great right and she went out with these people so she had to take a bus with this male friend of hers and they only knew each other for a month and the trip home she lays her head on male friends shoulder and i said thats too touchy and she says im controlling and i secure remind you we are in ldr for 6 months now and one time we had a big fight she went to her ex and ranted about me and she didn't tell me that this happened after 2 months have passes so am i over reacting over her so called BOY BEST FRIEND or what?
