I am in an academic program, and it begins in fall of this year. Last summer, the academic program held a required summer program for all of the accepted students. During the program, I experienced a phenomenon called "love bombing;" basically, I was given many nice compliments, put on a pedestal, etc. by a person with somatic NPD.
I realized what was happening to me (i.e., the love-bombing stage) when I came to learn about the NPD. Shortly thereafter, I read many books including those by Alice Miller, just because I really liked the person and wanted to better understand his experience.
Then after the summer program concluded, I reached out via email to my friend with somatic NPD to keep in touch. We corresponded over email, and it was friendly correspondences. Over the course of this year since last summer, our correspondences have generally been about once per month. They have been initiated by me, and I sometimes do not receive replies; but since I only reach out about once per month, it's not a huge deal. In addition to these email interactions, I have also sent a few gifts to my friend for holidays and special occasions (e.g., Thanksgiving and birthday). They are gifts like food items, books, games he likes, etc. I sent a gift about once a month. Sometimes, he did not respond when I told him I sent him a gift; however, other times, he does. When he did respond, he would always thank me for the gift. In addition, when he did respond, he would sometimes mention something about my nice generosity, wish me well, etc. He would sometimes respond with this alongside encouraging me not to spend energy and money on him, or to donate the money I would spend on him to refugees or people in need. I never replied to those "thank you" emails, because he was my friend, and it wasn't relevant to me about the energy/money/time spent on the gifts.
Here is my present situation and what I would appreciate receiving perspectives on, based on the above background information: recently, I sent an email to my friend. Again, continuing with the "once-a-month" interaction. He responded in what I view as a very out-of-character manner in the context of our past interactions. That is, he said he finds my emails disturbing and the gifts intrusive. I had not even brought up the gifts in this particular email, and the last time I had sent a gift, it was well over a month ago. Then, he said that he feels harassed and creeped out, and ended it with this line that we are classmates, and not anything else, not even friends. I responded to him with an apology for making him feel creeped out and harassed, and left it at that (after crying for about 2 days).
It seems to me like he is cutting off "supply" with me being supply. However, I also have heard that one with somatic NPD would never cut off supply. I appreciate any/all perspectives to explain my friend's behavior in the context of our friendly interactions to this point. Why would he give this impression that even though we have had mutual exchanges over the past 8 months, he is saying he feels harassed and creeped out? We are beginning the program this fall, and I feel sad because he was my friend, and now I feel like some kind of a creeper person.
