I want to have a married life and not live alone. So what I gather from all responses is the following

1) Show compassion and empathy and don’t complain. Encourage or remain silent and patient for her to maximize her happiness and efforts

2) If things improve, good ! If not, atleast I do my job and maintain my peace of mind and try to develop areas in my control to have fulfilment in career or sports or academics.

3) Children may or may not happen and I will leave it to faith and efforts from my spouse.

4) Major decisions in life, be it marriage, choice of education, careers, companies etc. are largely dependent on luck and experiences after taking those decisions. Even if I did have the maturity to evaluate better, no one can foresee all aspects of our decision and hence life is to be lived with what one gets. You may want something but will need to settle with something else, atleast a few times in life
