the truth hurts

so i met this girl online a few months ago and we started talking. she's twenty five and cute as hell and after a while of messaging we decided to meet up for coffee. turns out she has these really intense ddling fantasies and wants to play caregiver and little with someone who can switch between the two roles. i'm forty three and i've always been into this kind of stuff but never actually found anyone willing to do it before. so we started playing around and it was amazing. we were both so turned on by it that we decided to keep going with it. a few weeks in we went all out at her place for the first time, full roleplay and everything. she dressed me up as her little brother who was supposed to have run away from home but now needed help. i played along totally and let her be this stern but caring caregiver type. she took care of every little thing for me, feeding me like a baby and then giving me spankings that were more playful than anything else. it got more serious after the initial playful stuff though as she pushed me to do things outside my comfort zone. one time i was supposed to be having a temper tantrum and refused dinner because i was mad about something silly, and for punishment she tied me up in my pajamas and made me stay in timeout for an hour before letting me have it on a plate with a straw. i felt so vulnerable but also like this side of myself that i'd always suppressed was getting to come out. we talked a lot about setting boundaries though as it got more intense, and agreed on a safe word to use if anything crossed a line. but now we've been doing this for a few months and its become such a huge part of our lives together. im starting to feel like maybe she's pushing me too far, into areas i didnt think id ever be comfortable with. like there are times when it crosses over from fun play to something more intense that i need time to adjust to emotionally. not sure what to do about it though because the connection and chemistry between us is off the charts.
