Quick TL;DR Plate texts "I feel like your interest level has changed? Has it? I just want to know"

Been following RP for ~6 weeks. Currently actively sleeping with 4 plates, dating ~4 other girls that I'm working towards that goal. All these girls keep me pretty busy, allows me to be unavailable often and keep contact to a minimum. Was texting this plate too much (she's my favorite but ... there's 3 others anyway), after we last hung out (slept at her place) Wednesday I haven't initiated much contact via text, answering couple hours later or a day later. Meanwhile went on two dates and slept with a new girl last night so I was indisposed.

This plate is my favorite for a couple reasons: 1) She's super chill and fun, 2) She has her own shit going on 3) She's the most fun in bed

That being said she just hit me with this, "I'm terrible at dating games so I'll be straight forward. It feels like interest level has changed since last time we hung out. Has it? I.e. I feel like I'm bothering you. I'm asking because I'd rather just know."

How do I respond to this. Nuking this is not an option, and I'd rather not overreact and soft-next her, this feels like a comfort test, but should plates be giving you comfort tests? I was planning on texting her tonight to meet up after the bars, but now what?

I went with amused mastery and changing the subject, thoughts?
