Seeking expert testimony is a sign of strength. A personal relationship with a caring professional is proven clinically effective.
I have read through your letter and then re-read it to make sure that I understood all of the details and nuances that you presented.
The situation is not very hopeful to you. This woman is inexperienced, and very connected to her own culture which is very different than yours or to the UK culture.
She has broken from you and is trying hard not to fall back into a relationship with you.
If she did she would probably try to break it again. If she is unhappy in the UK then that in itself is too much pressure on her. She does not want to be separated from her family and is trying hard not to renew this relationship.
Her heart will never be in it fully, and you will not reach full happiness in this relationship.
As difficult as it seems, I suggest that you let this relationship go.
Things may change but it is highly doubtful. Any change will come from her and it seems that she has already made up her mind.
Try to look to the future without her.
