It's not irrational at all squiggle. You feel cheated and lied to, like t didn't want to touch you or hug you! I am sure what she said is correct and true, maybe she has different rules for different clients, like the client who was abused, they would probably not initiate touch or not appreciate touch! I can understand t having boundaries but please understand this is about t not you! You are not disgusting or gross, just t has strict boundaries in place for her own safety and needs!
I think maybe you should bring this up with t and say how it made you feel, she might be able to shed some light on why she only touches certain clients and why she has her boundaries in. Place! (hugs)
