Is NOBODY wrong in the post ? POST : So my fiance has joined the national guard and she went off to basic training for a few months when she got back she mentioned that some guys had flirted with her during the process, now I trust her completely and I honestly am not very worried that she would be unfaithful, but I don't trust the guys, and honestly I know if I was there they wouldn't flirt with her, because the ring on her finger but a physical person to support the ring would deflect the flirtation, at least I think, so I feel this anger at being helpless to stop it. She showed them her ring and said shes taken, and really I'm more asking am I an asshole in general? Does wanting to fight a man who flirts with your fiance and tells her that a ring isn't important asshole behavior or is it understandable and alright? One in particular called her "Shawty" which really irks me, I get that shes not gonna tell him to call him something different, and she had flirtatious nicknames since she is a girl surrounded by physically deprived men, but still, does my over the top anger classify as asshole behavior?

Sorry for the mobile formatting
TLDR: My girlfriend is far away and I can't stop men from flirting with her and that makes me feel violent
