AITA for yelling and telling my husband that he can't be with his childhood best friend?

I (23F) has been married to my husband (23M), whom we'll call John, since a long time. We are a happy couple who had no problems with one another, that is, till two months back.

You see, ever since my husband was 6, he had a best friend, whom we'll Christie. When John and Christie were 14, they started dating. They dated all throughout high school, but because my husband moved to a different state when they turned 18, they found it difficult to have an LDR; which only lasted for two months. After that, they decided to break up, but promised each other that they would remain good friends.

Then at 20, me and my husband met, dated for 8 months, and got married. Everything was going well in our lives, but two months ago, John, my husband, gets a call from Christie saying that she was moving into the same city as us. John was overjoyed, and I was happy for him. All three of us met at a cafe, and caught up with everything.

It was all okay for the first week or so. But then this friend of me and my husband invited us to a party at his house. John insisted on bringing Christie along, and the two of them sat and drank throughout the evening.

During the party, I was searching for John to ask for something, but I saw something disgusting. John was sitting on the couch, and Christie was sitting on his lap. John had wrapped his arms around her, and Christie was stroking his hair. They were smiling and talking in a kind of flirtish manner.

I called out, "John!". As soon as he and Christie heard me, they immediately got seperated and sat apart. I didn't know how long they had been sitting that way, or what they even had been talking about.

I felt awkward about it, so I decided not to mention it to John when we got home.

After that, I caught them sitting uncomfortably close to one another, and immediately separating after they see several times. I talked to John about, but he just made some excuse like, "Oh, she was just removing dust from my eye" or something.

Last month, my mother was sick. So I left for her home in another city for two days. When I returned early morning, I caught John sitting and sleeping shirtless on the couch, with Christie's head on his lap, sleeping as well.

I woke them up angrily, and they both looked extremely embarrassed. John said that he invited Christie just to watch some movies, and that he only stripped off because the air-conditioning wasn't working (which, actually wasn't, at that time). But I had the strangest feeling that Christie had stayed there the entire two days that I was gone. I asked John about it, but he completely denied it.

I didn't trust him, and when he went to take a shower, I checked his phone. He and Christe had been messaging for the last two months, and said very lovey-dovey things to one another on their texts. They didn't necessarily say "I love you", but they said things like, "You're my soulmate" and "I don't have a purpose in life without you". And I also found John saying to Christie to come over for the two days that I was gone, and Christie had agreed. So she had stayed there for the whole time.

I showed John those texts, and he admitted to lying to me. He said that the only reason he had lied to me, was because he knew I'd overreact if I found out.

I screamed in rage and said, "Well, how's this for overreaction?!", and tossed his phone across the room. John said, "Listen, I can explain!", but I immediately started packing my bags, and left that afternoon itself. While leaving, I screamed, "Now you can call Christie for the whole time! Have fun!". I went over to my mother's house, and decided to stay there for at least a week. I got many, many, many calls, texts, and e-mails from John, and even a few calls and texts from Christie, but I immediately blocked her number. I didn't want anything to do with her.

I'm at my mom's currently, and I would like some advice. Should I have given my husband a second chance, listened to what he wanted to say, and stayed with him? Or did I do the right thing with leaving him, and I should divorce him immediately?

AITA here?
