At least once a week, you'll see an article on Facebook about getting rid of "toxic friends." But I have sort of the opposite of a toxic friend.
I had a friend who was nice, and sweet, and generous, and always up for anything. When she asked "how are you?" she actually wanted to listen to an answer, instead of just exchanging a brief greeting.
And somehow, I found her exhausting. I would spend a day with her, and I would come home completely depleted, despite the fact that everything that had happened had been fun and pleasant and nice and enjoyable.
For a while, I felt guilty about avoiding this friend. I couldn't pinpoint what the problem was, and I felt bad about not wanting to spend time with someone who was so nice.
In the end, I decided it mattered less WHY this particular relationship was exhausting, and more that it simply was. I would never suggest to someone else that they should spend time with someone they found exhausting, even if that person was nice, so why should I?
I haven't seen this person in over a year, and sometimes I still feel like I should tell her why I "broke up" with her, although to be fair, she hasn't contacted me, either, so maybe the feeling was mutual. In the end, the conclusion I came to, was it was exhausting for me to be around her because I always felt like I needed to be patient, and sweet, and nice, and basically not me. Pretending is exhausting.
