I apologize in advance if this is choppy, I just found out and I'm still reeling and I guess venting a little bit here.

My best friend, who we'll call Hannah, and I have been friends for almost 10 years. We're both women and are in our mid-twenties. I've been on family vacations, her parents call me their second daughter and I call her parents 'mama' and 'papa'. We've both agreed that we're each others person and best friend, and until today I didn't think anything had changed. 

I am in the process of getting my estate put together and wanted to make her a beneficiary, so I opened messenger to ask for the best address for her (she's an officer in a military branch so she's not really permanently affixed anywhere) and I saw an unread message from her telling me she didn't tell anyone but that she got legally married over a month ago and they're just waiting for the right time to have a big party. I don't go on messenger often, and when she's on a ship she doesn't get cell service. I rarely use messenger but try to check it every couple of days in case she's messeged me. 

I'm so hurt by this. I'm trying to remind myself that this isn't about me and that I should be happy for her, but I'm not. She and her now legal partner (they don't identify with a gender) have been together for just over a year, they got married after dating for 14 months. Hannah has been known to become head over heels for everyone she's dated, and there have been at least three other serious relationships where she was convinced they were the one and were going to get married, etc. I don't understand the rush, but I would have supported her if she had told me what she was going to do and she knows that (I knew she was going to propose and helped her engineer it). 

We're both very busy people (I own two businesses) and have the kind of friendship where we might not necessarily talk for weeks at a time but when we do it's like no time has passed. I don't tell her every minute detail of my life, but I couldn't imagine getting married and not telling her. It's making me question our friendship and I'm not sure if I should include her in my will (which I think is just an overreaction but it's how I feel right now in this moment). 

AITA for being upset about this?
