Need an advice on my 7 years old Relationship

Hi guys I am 24(M) and in a relationship with a 24(F). It seems to me that we both are settled in our life. I am a graduated from a tier-1 institute and working as quant researcher in a leading quant firm. She is serving as a scientist officer in the Ministry of *******. He have not meet each other since 2023. I asked her many times should I come your home? Just to meet you, or anywhere else, but she never agrred. We used to talk very less. I want to make her talk, call and message her each evening, but she barely response the way needed in the relationship. I want to fight her, make jokes on her, make her laugh, but she communicates very less. Only thing she said everytime is that "I am too busy in my life, there are 100 things are going on, I can not give you time for next 2-3 years, I love you so much, if you want to leave you can leave, I will remain single for my life, if you are gone."

I asked her, to revel our relationship to our parents but she never agreed. I love her and attached to her too much. I will never able to give her place and replace her with any other girl, but I need to accept that this is not common. I am busy too in my life, but always manage to make time for her. Even I think, a person is busy only for those who they not like to talk with.

I am totally puzzeled, what to do. I want to detach myself from her (can not unlove her), so that I feel free from the fear of loosing her. I think I can not detach, with living in this relationship, but when I tried to break this for my mental peace, I become too emotional and get back to her. I have very less EQ, when it comes to my love.

She is even keep blocking me all the time and only calls when she want to talk. I am not selfish, but I just feeling, I have no importance in this relationship.

This is all my side of thoughts and story, as what I see. Not sure abot her side. What should I do now. Please advice. I will be tankful of all the sincere oulook. Please do not comment unnecessary.
