Some context: I am 23 nonbinary in a poly relationship, with a 22 gf and 22 bf. I have struggled with mental health issues most my life so I find joy in the small things like buying myself dumb plushes. My recent plush hyperfixation has been build a bear frogs. Today i went to the mall with my partners. We were walking around and finally I was like i’m gonna go into BaB and buy myself something. I didn’t tell them why but it was because i’m finishing my 3 month IOP next week and wanted to celebrate by buying a plush i’ve had my eye on for a month. My bf comes in with me while my gf goes somewhere else as she doesn’t like BaB. I go and grab what i want and tel my bf to grab himself something so he does so we do that, get to the register and i get ready to pay when gf walks in. She sees the total and right away starts making comments about how much it costs and that I really shouldn’t be spending my money and so on. I get nervous but proceed with buying. She then tells me we are going into a recession and that I seriously need to stop spending my money and that I don’t have money to spend(despite the fact i work a full time job). She makes me feel very bad about this because she’s doing it in front of people. I tell her an excuse that I was buying it so i can have some small joys today because I was upset and she was like that doesn’t matter find another way to do it and that we shouldn’t come to the mall anymore. I get really angry and start to walk away and we make it downstairs and then when we get outside I tell her the official reason and she doesn’t say anything. I cry on the way home and she doesn’t apologize or anything. I get home she drops me and my bf (who hasn’t spoken up at all the entire time) at my house. I send a text like an hour later “hey i’m really hurt. let me live my life the way i want please”. She doesn’t reply. I send another message just now to the gc explaining how it all made me feel and still no reply. Am I the asshole for all of this?
