Question

Hello guys Do you know how to get rid off a fake attachment to a girl that I wasnt even in a relationship not even a friendship we were just introduced to eachother by mutual friends, when we met several times by a chance we just got small talk and thats it, 5 months ago when I asked her on messenger if she want to get to know better eachother she rejected me. Everytime I see her in city I got that weird feeling of a "why didnt it worked out" I think I got my imagination get to me too much, cause I expected something more because I never got a girlfriend... The only thing I know is that I want to prove them wrong and regret this cause Ima going for best shape in my life spiritually, mentaly, physically and financially
