Gabrielle? Is it a suitable name for me?

My English name was Gabrielle. It was given by a teacher from Scotland when i was in college. He told me it means angelic. I believed it must be a beautiful name. I used it for over ten years until i met an American one day. He was quited surprised at my name. He told me in his country it was only used as men's name. I felt rather ambarrased. Then he advised me to change it into Gabriella. So i used this name now. But i am still confused. Is "Gabrielle" really only for male? And i can't find "Gabriella" in dictionaries. Is it a common name in English-speaking country? If it isn't, would you be kind to give me another better name? Correction: Why do you want to change your name? Whatever the name by you are known is the suitable name for you. There is nothing in a name, our deeds are important. A person knowing by the name of angelic and acting as satanic; you just think of the contradiction. Be a nice person by deeds and give only love to others and avoid any kind of hurting others, then any name is beautiful. You have a beautiful name , make it meaningful.
