In order to do this she would have to go against the teachings of Islam. Whilst it is allowed for a Muslim mand to marry a non Muslim woman (although though she has to be a woman of the book i.e. Christain or Jewish) it is not allowed for a Muslim woman to do so.I can not imagine that her family would be happy of this situation and would probably disown her.
As has already been said she could not get married in Egypt.
I could not imagine that she could live in Egypt either after the wedding as if it was known that she was Muslim and he was not then the comminity where they were living would be against them.
So she would have to leave her religion, her family and her country.
From the sounds of your post she has only met this man briefly and has fallen in love with an impression rather than a reality. With no common language there can be little deepth to their reltionship as yet.
She has to be prepared to all the above for a man she has only known briefly and superficially no matter how deeply she loves him.
And then where are they going to go, what country does he come from, what is the likelyhood of them granting her a visa.
What do you think an embassy would make of their relationship, would they believe it to be a genuine one.
If I was a betting person I don't think I would be putting money on this one.
