does it annoy you when people assume..., to know what you're talking about? Options

here's the thing...
recently, one of my school mates signed up for xanga. i used to have a fling with him... now, we're kinda friends.. kinda not.. i don't even understand it...
anyway..! he found my account and started reading the things i wrote..... his name appeared a couple of time in some of the entries.. those had to do with how i felt/feel about him and what not.. later, he finds this entry that's about a night i spent with a guy.. there are no names in it; just pronouns.
then, he remembers about the time i told him that my family won't be home and i asked if he wanted to come over. his answer was vague and eventually, he didn't come. i didn't make a big deal out of it cuz i my other friend, who was visiting from the philippines, came over.
the point is, he thinks i was talking about him and that i was being "f**king delusional"!!! argh...!! i hate people like that!!!! i mean... why the hell is he assuming that i was talking about him!?!! i'm not desperate at all!!!! plus, he doesn't like me anymore and i don't like him anymore.. (but i'm not sure if that's clear since he did this..)
now, he's saying that i'm "f**king crazy" and "living in a fantasy world." bullshit!!! then he was like, "you're retarded" and some other crap like that.. i mean.. please!! the world does not revolve around him and it's not like he's the only guy i'm seeing....!!
well... yea.. that's enough of my ranting...
...so....
have any of you ever experienced that..? like people assume they know who or what you're talking about, and they think they know you..?? don't you find that rather annoying or aggravating..????
