This stands out to me. Whether she's your soulmate or not doesn't really matter compared to how you feel about her.

Sometimes people come to teach you things maybe there's a hidden lesson from continuing with her. maybe she will end up seeing the same way you do with religion and drinking. the vegan thing (i'm vegan) will come with time no matter what. or maybe you will be so happy eventually with her that those things wont matter to you anymore.

Either way won't it always make you curious what could have been with her if you let your requirements lead you away from her?

Plus maybe god wants you to learn stuff from her in order to prepare you for your soulmate. or maybe she is your soulmate and you choosing her will show you that to be the case in time.
