AITA? My girlfriend dyed her hair and lied to me about it and now she is mad
My girlfriends hair is naturally very dark brown and I like it. She asked me if she could dye it and we had a talk about it and picked a color we could agree on. A few weeks later she told me she was just going to get it straightened. While she’s at her hairdresser she tells me she is getting it dyed the same color we agreed again upon earlier. Then she comes home with it dyed about 3 shades lighter. I tell her that I am upset and I don’t really like the new color. I also told her that I wouldn’t have been mad if she at least told me she wanted it that color. Now she is saying I’m a bad boyfriend and I should just support her no matter what. This isn’t that serious but AITA?
Edit
Sorry forgot context
She makes me talk about my haircuts and I wanted my hair dyed and she said no.
