I knew this would happen, I was stupid enough to let it happen and it still hurts when it happened

I started a friendship with this girl I liked when I first met her, even though I was told from other friends nothing could happen and it wouldn't go past the friendship level I didn't mind so I just stayed as a friend. After months of talking she started developing feelings for me, I learned this a few days ago and yesterday we confessed that we love each other to one another. We want to be with each other but because of her culture she can't, she's indian, i'm black. I knew that she couldn't get into a relationship yet I still got close to her and now I feel stupid for letting it happen. I found love and lost it so quickly.
