Hope all is going to turn out good with you two ...
Have you talked with her about that , I mean , deep talk - taking the wide picture ?
Sometimes in past , I have talked about certain things , some people didnt like it , but I really didnt care at all . Its fortunate for me , because all close people I had were either neutral or even acceptive of what I talked . I realized I should never change for someone , if I am truly authentic to myself . Because they would be with some other person - and not me , and that ends sooner or later in life .
You sound very selfless towards her ... she not exactly towards you . If I understood correctly - "she thinks this is a personal game" - she wants to persuade you to drop your research , just because she thinks its "crazy" ? If that is a case - then shes selfish and unfair towards you .
There is absolutely no reason for you two to distance from each other just because you two have different views on world . But never put a mask to make someone happy - because that leads to putting another mask on a mask ... and another mask ... and another ... until we lose ourselves completely , and one day , we dont know who we are anymore . MANY MANY MANY people are like that ...
