It is possible that you love her as a friend but not necessarily as a girlfirend. Try and think back as to why you got involved as more than friends. You clearly care for her.

As to not finding her physically attractive, well maybe this is the image you have of her in your mind that is becoming messed up by your doubts and well when you are back together then it is worth thinking about that. It can be hard when people are away.

Yes it could be pre-marriage jitters or it could be doubts cos she is away.

But I do think you need to think carefully about how you feel, think about why you entered the relationship. Think about whether this is just cos she is away. It is good that you will honour your commitment and yes you could both di fine in marrriage as friendship is important but if you dont feel more for her than as a friend it could also be difficult as well.

I am not good at advice but one thing I will say is listen to both your head and your heart.
