Would it be better for you to get a new T, what do you think? If it is a small town with very few Ts it will be hard to avoid dual relationships. Otherwise these are really best avoided if you have a choice, esp. as you have already voiced doubts and worries. This is a valid concern, and an important boundary issue. It's nothing to do with maturity: you shouldn't have to handle things like this in the first place. Good luck,
