Heartbreak

Hey guys so I dated this one boy and thought nothing was serious in terms of dating but little did I know I was falling for him very very hard ...he was there for me when no one else was like at a school dance he kissed me and told me he loved me and I felt my heart melt...I’ll never forget that day ...anyways we broke up for like 5 months now and I’m still heartbroken and cry at night although I know nothing will be the same it hurts really bad because I still love him and he has my heart ...any advice girls ? And he was so loyal and sweet but idk things have changed but we have talked through this summer which makes me happy/sad knowing he isn’t mine anymore Please I don’t want to feel like this anymore..
