Honestly, I think for the sake of your own mental health that you should take a break from this girl. Maybe a few years down the line, you will both be out and comfortable enough with your sexualities to pursue a relationship. But for now, all it is doing is driving a wedge between you both and clearly having a negative effect on your mental health. Wait until you are both on the same page and try again. Best of luck Shelby, I hope everything works out in your favour and in the mean time, take care of yourself, it'll be worth it in the long run
