AITAH for getting a hairdresser appointment without my husband "knowing"?

My (28) husband (30), I'll call him Joe, have been together for 7 years. Married for 3. Joe and I are normally very loving and haven't had any trouble in our relationship until yesterday. For a month I've been going off about a haircut at the local hairdresser. I've told him several times, but the entire time he have had his nose into his phone and this have happened a lot lately. I asked him if I would fit a bob, or just shorter hair or even colour! He would just nod or say "That's your choice", not even looking up from his phone.

Fast forward to Friday, I booked an appointment at the hairdresser and told my husband about it. He nodded and said "good" with his nose in his phone yet again. (This problem haven't been before). The appointment was yesterday (monday). I get ready and go to the appointment after saying bye to Joe and he say "Bye, be safe" not asking where I was going, but I figured he knew since I literally told him on Friday. Anyway, I arrive to the hairdresser and cut it a bit shorter with some blonde highlights.

I loved my new hair and was excited to show my husband. When I got home Joe finally looked up from his phone and got furious when he saw my hair and yelled "Why did you change your hair? How much did that cost? Why didn't you tell me". I was at a loss of words and said calmly back "but I told you on Friday that my hair appointment was today. I even mentioned it a month back but you've been so obsessed with your phone that you probably don't even notice me anymore" I do regret the last thing I said, because he got even more angry, packed a bag and left to his mother's. So did I overreact? Did I do a wrong thing not telling him more direct?

UPDATE! Thanks for all the support. I've been on edge lately after getting comments about Joe cheating. I don't know anymore. For some info. Joe works at the local hospital. He is usually very busy with work, but always makes time for me and takes me on dated etc. We don't have any kids by the way. We have a few mutual friends (mostly males), but nothing to get suspicious over. Other than that he has very few friends and isn't close with anyone. I also have his password to all devices, but never had the suspiciouns to check it. As I said we have always been loving in our relationship and nothing to doubt his love to me.

I know he went to his mother because I have his location and he has been there the entire time. He texted me earlier today and said he was sorry for the way he acted and loves my hair, but got confused because I "didnt tell him" when I told him a month before, leading up to now. We called for a bit and he understood where I came from and my situation. Yet he refuse to come home just yet... I'm starting to suspect cheating and will be checking his computer later today. I know that's invading his privacy, but I need to know.

I'll update as soon as I can. Also thanks for bearing with me. I'm not English and I have dyslexia. Again thanks for the support.

UPDATE 2! Hello people. I do apologise for the long wait for the second update. A lot has been going on lately and a sleepless night. I'm currently looking for a new place and I'm bringing our cat! (Fenris). I went through his computer when he was gone (he is still gone), and I found messages of him and my bestfriend, call her Hannah (27F). Im so hearbroken. Hannah and me have been bestfriends since diapers. She is my ride or die and I go to her with everything! I tell her everything and she tells me everything, or so I thought.

Apparently Joe and Hannah have been having a whole relationship for a month now and that's why Joe has been so obsessed with his phone. I truly didn't even suspect cheating before I went to Reddit about the matter. All the late work shifts finally make sense. He is still at his mother's because he invites Hannah over to her! (Of course when his mother is away). I saw the recent texts between them on his computer telling her to come over. He thinks he is smooth with deleting it on his phone, but he forgets he have the same socials on his computer (undeleted).

So since I got the truth slapped hard across my face, I have made my own bank account, (we shared). Packed most of my belongings and gotten my cousin to help look for a place. I earn enough money to live on my own comfortable. To be honest Joe wasted my money on useless stuff he never needed, so this is perfect for me! I also called a divorce lawyer because whatever someone says, I'll never be able to be married to Joe anymore. I'm still going through my worst heartbreak, but I have good friends by my side. Joe doesn't know that I know yet, and I won't tell him until he gets home and sees me gone, with all furniture, our cat and perhaps glitter all over. I saw a video of someone doing that once and its hilarious. Pluss I'll get out some anger throwing the glitter around. After he gets home, I plan to block both Hannah and Joe. All communication will go through the lawyer. Thanks a lot for some harsh insight about the truth. I'm happy I know.
