Once a month therapy? What's the point? I wouldn't be able to have a good trusting relationship with my T...
As for your T- I don't know. From what you have described I wouldn't bothered to spent your money (not his time- remember YOU are paying him for his services) on him.
However, I think the advice to work on relationship with your mom is good. Parents, like it or not, are really important in our lives. Even though she wasn't good mother when you were growing up she can be now. Seems like she is willing to work on that with you.
