First of all welcome to the forum, and second of all i think many others will agree with this here at VC your not judged my your political affliation so ya hala.
As to the the opinion you need:
There's this thing called using your mind vs. your heart and your issue basically revolves around that. You are the one who has to choose whether youre going to go with your gut heart feeling or your mind.
I don't know how old you are to know how serious this relationship might be. In my opinion if you know for a fact that this relationship isnt going to last and its just a fling dont let either of you get hurt.
The importance of religion varies in each and everyones lives. To you it may not be the end of the world but for a person like this girls mom it could be everything. If you do decide you want to go ahead with this relationship before proving to her you respect her religion your going to have to prove to her mother. Its obviously something normal for parents to worry. But i dont know if youre thinking ahead and whether or not u think that u will be able to sustain a life with two religions.
I personally don't see religion as a barrier between two people but i dont understand what some may worry about. one thing is for sure dear religion doesnt make or change a person.
and the way this girl is taking ahold of this problem is very wrong. you have to explain to her that hurting herself isnt gonna get either of u anywhere and that her leaving the university is not going to change what her mother thinks. She has to make the decision of either approaching her mother like an adult or her self acting like an adult and weighing the pros and cons of you guys being together. nothing is simple and an issue like this sure isnt but with two bright wise and open minded people i think ull be able to over come it no matter what the decision is lay out ur pros and cons.
i hope it helped a bit
good luck
