My friend changed my name in his phone!!

So I’ve only come out to one person so far but did I make the right decision. He has been so supportive and generous with me and the other day he asked if he could change my name in his phone from my birth name to Aislin and like No. 1 intense gender euphoria ensued and No. 2 it was so kind and thoughtful of him to ask cuz he said he did change it at first when I came out to him but then changed it back cuz he said he was afraid that like he might slip up and be tryna show mutual friends a funny text from me or something and accidentally out me to someone before I was ready so yeah he’s just the best fren. 💖
