Baby Name Poll

I gave my daughter a name I’ve always loved, it’s very beautiful and feminine but she really disliked her name. When she became a teenager, she started going by a more unisex/masculine name, which is weird since she is really beautiful and super girly and loves pink everything and not a tomboy in anyway and fits the feminine name I’d given her more than a unisex/masculine name she goes by. She is now in her late 20s and is about to get married since she will be changing her last name to his, she is thinking of going ahead and changing her first name to the name she has been using since she was a teen since she goes by it socially, professionally, and everywhere she goes. It broke my heart when I found out she disliked the name I’ve given her and went by a different name but now it hurts even more that she will be officially changing it. My husband and I are both upset about this, how do we learn to get over it and support our daughter?
