From your post over and over again, you seems so desperate, missing her, perhaps.
If you really do love her and as many have advised you to marry her back home, then you may do that.
No one can't stop you to pursue your dream,.
You should think clear and ask yourself if it is really love or just lust, prior taking a big step in your life.
I don't want to judge, yet I do believe that:
- Love is not the reason to make someone to convert to other religion
- A good lady shall stay with her family, before marriage, not the man' family. (Why doesn't she go back home and you can ask her hand from her parent nicely)
- Things happened for a reason.
On the end, it's your call, dear..
People advised you this and that, and you don't seem satisfied enough. Never take any decision when you are angry or confused.
Good luck.
