ALR's entire love language revolves around buying people things. Especially when she's in the love-bombing phase of BPD lunacy, she just spends tons of cash on absolute garbage. (Then in true BPD fashion, she builds up resentment about how much money she spends on that person... 'round and 'round it goes.)
This is separate from her trying to financially dominate someone and make them dependent by paying all their bills and rent and not letting them work. Related, insofar as it's ultimately about control, and as far as money plays a central part in her value system (though not so central as calories). But she can't stop herself from buying every bit of bullshit that catches her eye, so she thinks that everyone else actually wants all that shit too. Like, she can't conceptualize someone seeing a t-shirt, say, at the store that they think is funny or cute, and then not buying it. Not because it didn't fit or they didn't have the money -- just because they didn't really need or want another shirt. (Similarly, most people can express a fondness for ice cream or whatever without needing to buy it because they see it. Though on that note, I've often thought that grocery stores are ALR's happiest place on earth -- an absolute wonderland where all consumption intersects. Air conditioned, too! And with scootypuffs!)
So I have to wonder. What would happen if the object of her affection didn't want dollar store trash? I mean, we'll never know because the only people who are willing to pretend to be interested in her are white trash grifters who share her fucked up consumer impulses. But what if a girlfriend said to her, "Hey, I appreciate the gesture, but I really don't need any more candles/key chains/stuffed animals/snapbacks. I know you like buying me things, but please stop doing this."
Her tiny brain would explode into a massive tantrum about how they didn't really love her if they wouldn't accept her gifts of trash. It would be an actual, honest-to-god opportunity for her to self-reflect, analyze, and grow as a person. But again, she'll be spared that because there's lidurally no reason for anyone to get involved with her if not for the Dollar Tree Shopping Sprees.
Just thinking out loud here, I guess. Reading about Wipey has me all contemplative.
