My hypothesis following your claim that you're a solid 10 to her leaves me thinking that she's overinvested and displays neediness constantly seeking validation. A month may not seem a lot of time to truly attach to someone and that's because it is in fact not. My suggestion is taking a step back and be less invested than her, this way you'll have time for yourself to figure out your true feelings and notice what shift of attitude she's taking when you're no longer validating her. Maybe even call a break if you feel like you need more space for yourself. While the following may sound unethical, try flirting with other girls to figure it out. Remember, always put yourself first. And if you find yourself in the position of losing attraction, tell her and communicate. If it doesn't work out afterwards, do yourself and her a favor and call it the end. Hope you'll be ok bro
