I have a friend in office with whom I had a causal relationship. Suddenly he is feeling guilty about it and doesn't want to talk to me. Also, I spoke to his friend about his ex girlfriends which he didn't like at all and then he is blaming me that I shouldn't have done that and now I shouldn't force him to talk to me. But I am really very upset with his behaviour. I have always considered him to be a great friend but the way is reacting to things is really absurd and making me nervous.
Bcoz of all this I am not able to focus on my life and work both as we sit exactly next to each other.
I am not understanding how should I deal with him and this matter as a whole.
