i think it’s the implication that what is stopping you is the fact that you aren’t attractive/don’t have game like that instead of you just only having eyes for her. the thing stopping you from thinking about/interacting with other women in that way should be your love for her and your loyalty, not your inability to pull women. obviously still something she needs to work on not being so sensitive too, but that’s probably why she’s upset.
there should be more trust. with my bf i know he's attractive, thats partially why im dating him. so for me to think other girls arent gonna find him attractive too is unreasonable but its his responsibility to not act on it and tell them he has a girlfriend. when she comes to you with concerns just tell her you love her and even if you do get hit on that doesnt mean you'll reciprocate. you want her and a random girl on spring break isnt going to change that
exactly. while she does have to work through the insecurity and trust you, the response given was like a “well i couldn’t even cheat if i tried” implying that if you could then she would have to worry about it. something that will help her work through the insecurity is being reassuring in a way that emphasizes that she doesn’t have to worry because you would never even consider another woman.
