From Redditor u/aidan_entity:

For context, both my friend (16F) and I (17M) live in Maine, and a couple hours away is this amusement park; let's just call i[t] gootimetown splishtown. Tickets (for my family at least) are kinda pricey, especially when you add up the cost of gas to and from where I live. My mom was on vacation from work one week and asked me if I would like to invite a friend because she was able to get discount prices from the town hall rec program since not enough kids joined this year. I immediately thought of my best friend; we'll call her v. I asked v and she immediately said yeah and it was exciting... until we got to the park.

We went on a few waterslides and splashed around, and once we went to get food and relax for a while, that's when it got a little iffy. We were talking about a little trip she was going on the week after, and I started talking about the last time all of [us] hung out, which was my birthday, which I spent with her and our friends. And she randomly said, "Ugh, the last time I was truly happy was last time I was there with (another friend)," which was wayyyy before my birthday and any other hangout where I was invited or invited her. I have really bad abandonment and trust issues and most of the time I can't be out with my friends for too long without thinking I'm a horrible person and they all secretly hate me. So… the mention of the last time she was "truly" happy made me a little but upset and I admit I was snippy when I replied, “You mean before the time we hung out for OUR birthdays during winter break together?”

And idk if she thought I was joking, but she just said obviously yeah, and rolled her eyes and started laughing. The entire rest of the day she kept going on and on about how she was so excited to leave and go on a road trip with her friend (her friend constantly criticizes her about not having a job and talks sh*t about literally everyone). She kinda ruined my mood for the rest of the day, and I brushed it off and thought it was done. News flash: It wasn't.

We were going to go on one last ride and then she said, “This would be a lot more fun if (friend was here),” and I had it. I got so annoyed at her that I started crying and said, "Fine, next time you want a ticket to funtown that was FREE, mind you, you can ask her if she can put in for time off from her JOB and pay for both you and her tickets, and then you won't have any complaints. And I walked away telling my mom where she was and that I was gonna go to the car. I had never blown up like that and I felt bad, but she really hurt me. I just wanted to have fun with my best friend and I still really care about her, but I just don't know what to do rn. Aita?
