It is normal, as a human being, to be affected by other people; Because people come and go, we all change and sometimes the one you love doesn’t feel the same for you and you can’t blame them because you can’t choose who you fall in love with.
Your biggest mission in this kind of situations is to not destroy yourself by forgetting that you are special too, don’t forget to love yourself and the most important to value yourself.
Life is a beautiful thing, never stop loving and doing what makes you feel happy; It’s never wrong to love… So until true love finds you respect yourself by feeding your heart and your soul with actions and things you love and make you feel happy.
P.S. - There is an old saying about ‘waiting’; Better things happen to those who wait.
