I am sorry your therapist allowed this minor occurrence to become a larger issue for you. Affection is a powerful form of connection and touch/body language is often used as form of communication. Touch can provide relief, give attention, distract from other overwhelming sensations and yes, can show affection. What is important for you to evaluate for yourself is how was your body approached and how has your relationship been defined with this person.

((((whispershadow)))) makes a good point here


If a family member who you are close with crosses a boundary that you yourself were not ready to cross, then a conversation may need to be had. Maybe you had a difficult time processing this occurrence because the other person may have set a boundary that they became ready to cross, but did not find a way to discuss with you first?

Before trudging through history of good touch/bad touch, maybe try re-establishing boundaries with your friend, therapist and family member. What you are asking in not unreasonable
