Search Results: hid my stuff

I have a best friend, and we've been really close for a long time (8 years almost) and we've helped each other through a lot of things.
Then a couple of years ago I introduced him to one of my friends and they became close really quickly, it was all good, and he fell for her, I was really supportive and helped him.
Then earlier this year she and I had a fight and we stopped talking to each other, but I told him to continue being friends with her and I still help him with her and everything, even though we don't talk.
Then, they started doing things together that he used to do with me, like watch anime, or listen to our favourite groups new music. I didn't care too much at first because he is in love of course he is going to want to do those things with her too, but then he stopped doing stuff with me, and our conversations became really boring or only about her when he had a problem with her.
Then a few days ago I went to a party and saw her, she looked at me and sneered and walked away, I felt awful, and asked him if he had warned her that I was going to that party and he said yes, I didn't answer because I was having an anxiety attack which I'm prone to, and he knows, and I was having one because he had warned her and not me. One of my friends talked to him and told him that she thought that being there for a friend is better than being there for the girl you like because friends usually last longer than someone that you like (who doesn't likes him back, and I have told him that but he still preferred her) and he told her that if he liked someone that means that he is really good friends with that person, so he doesn't think that he has done anything wrong.
by the way this is only an example, there has been other times that he had told her things and not me, and we had told her things about me (which I don't care because I have nothing to hide, but he could've asked)
