Will a girl lose interest/attraction for a guy if he becomes overly familiar & she just uses him as a therapist even if she likes him?

Now, why do you think she would be comfortable and willing to use you as a therapist... in particular that she most definitely will not be talking about you and rather some other guy that she needs your input on how to she can get him to like her better? Like her asking you about different BJ techniques that he may enjoy better... like "if I were to like to scratch him under his balls while I gave him a BJ, help him cum quicker... he like takes forever (for me the answer would be yes, it would most certainly help me big time!) Besides, she would most definitely have to like you enough to even be comfortable asking you that. What can I say, she has a very good friend in you!
