<human>: I have a friend who I have known for more than three years. Whenever I introduce him to a friend of mine, he starts contacting them and hanging out with them without me. Recently, we had a big falling out (due to something completely different) and out of respect to him, I didn't hang out with his friends or really contact people who were closer to him because I didn't want them to have to choose sides or be uncomfortable. Little did I know that he's been hanging out with my friends, inviting them over to his house for dinner without me. I feel really left out because these are people that I've introduced to him and they're my friends. I confronted him about it and he is adamant that he has done nothing wrong because they became his friends as well the moment I introduced them to him. Am I in the wrong for feeling this way?

<bot>: Am I in the wrong for being angry when my friend goes out/hangs out with someone I introduced him to without me?
