So, in this case I feel like I'm going to be the asshole. I have a friend, and he is really nice. He hasnt done anything wrong, exept for trying to talk to me a lot randomly, and sometimes he would follow me a bit, while talking to me, even though its lunch time, and we don't eat together. He is a nice dude, and he hasnt done anything wrong. But recently I've just been feeling kinda...annoyed around him. Idk. He has done nothing wrong, and I feel like I'm being rude because I'm sorta ignoring him (aka when he talks to me I still reply, but dont really add more to the conversation). I feel like I'm the asshole. I have cut off only a few other friendships, one of them was a valid reason, but the other was not so  much. The second friend I've kinda wanted to stop was with this one friend who sat next to me on the bus. At one point he got mad at me because I wasnt talking to him. Mind you, I'm pretty introverted unless around close friends or family. Also he pretty much claimed that he "knew" I had a crush on him (which I didn't) because I apparantly blushed around him. I'm not sure if that's the reason why I didnt wanna be friends with him, but that may be it. So, AITA for breaking off these friendships for (mostly) no reason?
(I'm fairly new to posting so sorry if this kinda sucks.)
