It’s not that I don’t trust her, it’s the other guys I don’t trust. I feel it can give off the wrong impression, they can develop feelings and it rubs me the wrong way, but I understand where you’re coming from. Ultimately I’m not gonna be controlling or abusive, but it’s always not gonna sit right with me
You’re gonna have to trust your girlfriend to choose her friends well. She, hopefully, knows how to judge someone’s character on whether or not they’ll be a good friend or a creep. If there’s a specific guy she’s hanging out with who you’re getting bad vibes off of, let her know, but otherwise trust her judgement and be there for her if things go bad. Don’t second guess her judgement and don’t say I told you so if it does go bad, just trust her and be there for her.
