thanks for the information Teak

I did feel eventually that he is a narcissist, but didnt know there are types to it.

Read about covert narcissist after reading your post, and it does feel like he is one of em.

Because, until I was close to him, he used to be very nice , and overly grateful, and then suddenly he started pulling away.

Before this I used to feel he is not at all judgemental, but eventually after spending a significant amount of time with him during these recent months , I realised he is such a perfectionist he keeps judging people on the basis of the same metric of his efficiency, and that made me so uncomfortable, how he didnt understand I am not like him and donot hold similar aspirations and have a lot of other interests apart from academics.(although he never directly judged me like he did for others, but I didnt feel very supported either, during the last two months)

To anyone who is even a close friend to him, wouldnt realise this side of him, most of the ppl who have interacted with him, think of him as a humble reserved guy.

I am in general a bit anxious and a bit insecure abt myself ingeneral due to some events from my past,i am still learning to get over, although it doesnt show up easily on my face, but people close to me know that abt me. So a narcissist is the last person I need to be around

Nonetheless, it doesnt matter anymore, analysing this, because it is over now i guess
