If I may comment as a young(er) generation (I am early 30s now): I met who I wanted to marry when I was 29, and proposed to her at 30. I think she will be fine. I honestly think your daughter having to re-settle her life to find someone who shares the same wants in life out of her will lead to longer term happiness. When I was 25, I was dating someone long term whom it was kind of similar, I adored her, but ultimately we were not compatible. I am much happier now with the person I adore and am compatible with.
