It wasn't instantaneous cure, it did say that it had been a couple of months. Just why would anyone want to read superfluous pages of him repeatedly hugging and sometimes no conversation before returning to work. 10 count was different because he was an actual doctor while this is just two people trying to find a way to make their relationship work. Also, in 10 count he had germaphobia not just being afraid of people.
My best friend had worse trauma and she didn't like guys touching here
she finally fell in love and is with someone, she was worried about that trauma of hers and how it would effect her relationship but surprisingly enough the power of love was strong and she didn't hate him touching her she enjoyed it
4 years of trauma goes from no progress to sudden cure. Would have been more realistic to have him start warming up to touches that weren't sudden, then touches from just his lover or something. Not just bam, full cure, can have sex freely, and touch anyone. I think that is one thing 10 Count did right. When the doctor told him he would never be fully cured, but could learn to manage the condition and make progress
