How long does it usually take to establish trust with the T?

I have trust issues and have a hard time trusting people but it didn’t take me long to notice that I had started trusting T. He actually doubted my trust at first because he thought that it would take longer. But I explained it to him and he said that he did believe the trust was there.

I’m curious as to how I was able to trust T so much earlier than in the past. Is that unusual for that to happen?
