I didnt see here anything which is boundary crossing... Texting and sending emails - most of us do it znd as understand your T doesnt mind so you didnt cross his boundaries.
Talking for more than over without paying - its just nicr and caring and most of us would be happy if our Ts did it, I dont see it as crossing boundaries. I was talking to pastor for more than two hours and fot free and I was really thankful and suprised he is so good to me and felt little bit guilty for taking his time but it was his choice. If T has a time to talk to you more and he doesnt ask you to pay for his double job you should feel fine and its nonsense to search there boundary crossing...
