I'm in a situation that I don't know how to solve without hurting the other person's feelings.
Basically, I requested some help from a person which have accepted promptly. Help that requires motivation, friendship and time...... (would take a long time to accomplish, one time per week, some hours), things that this person is happy to do and even shifting hours of her life to help me... and all for free. (and no, we're not talking about my therapist :P )
Meanwhile, I've "used" this person help 2 times and I really would not want to continue with this help for a group of reasons: distance to this person; methodology/habits of this person that are very different to mine; and some other things of my private life that I want to keep secret of this person but that affect my availability for the help I requested for.
In my mind I've thought of all kind of excuses to say to this person that is very kind and friendly, but somehow I think I will always hurt her feelings.
