It’s my fault that I took my guy friend for granted

I guess everybody tried to warn me about the rotten ex boys friends I’ve had and I was told it’s because I’m avoiding a real, true, loving relationship. My best friend said my guy friend (let’s call him Eddy) as what she’s been told has liked me for a long time and I should just give him a chance.
My older sister really hit me hard with the truth and told me I should open my eyes and see that Eddy has always been the one for me since day one and he’s always loved me so much no matter what size, height or what I looked like. He’s asked me out so many times besides Valentines Day or every school dance he always asks me. I always throw him in the friend sized and when he had a girlfriend, I got jealous and angry.
If I don’t see his worth, he will move on and someone else will. I guess I realized that my heart is after Eddy all these years and he was right, my heart will be after him. He’s been in my mind and every love song that plays, he’s in my mind or I see his face. I try to fight it away but it keeps coming back.
I asked him earlier if he wanted to hang out. Eddy said it sounds great and glad I woke up and realized his worth but, he’s moved on and he doesn’t want to be let down again and he met someone else this week.
I was so happy for him, but inside my heart felt like it got stomped and my world shattered.
It was my own fault because I took Eddy for granted for so long and I never fully appreciated him. He said he will always love me and have love for me, but I’ll always be his close friend.
Wow…..but he had every right to move on and find the right person.
I don’t know what to do. I can’t believe a let a great guy like him go. I’m happy for him but why am I so heartbroken, and crushed? I’ve been crying my eyes out so much.
