Is AUTHOR wrong in the post ? POST : Soo,

I Have a friend group that I met about 2-3 years ago. (they already knew each other for like 2 years i guess). I met this girl before the dude and I instantly liked her quite a bit. After that i met the dude and we got along really good and he eventually told me that he had a crush on that girl and from that point on I was helping him try to get her because he is a really cool dude and I think he deserves it although i really liked this girl (maybe a bit too much). So both of them talk with me about the problem with others and in the end they didn't get together although they both loved each other. You should also know that they both have "strong characters" so they and really stand each other. That whole process was 2 years. Now is where it becomes tricky. For those whole 2 years i had had to live with the burden of having feelings for her and i finally decide to confess to her. Right now I'm living away so didn't really think it would become anything and I didn't even know if i wanted us to be more but i just had to tell her because i couldn't hold it anymore (maybe kinda selfish). so i call her and confess to her, she is silent and hangs up after like 30 seconds. I realize that she doesn't feel the same for me so I write her that i don't want us to get together or anything but that i had to get this off of my chest but i see that she doesn't receive the messages. A few hours later she sends me this huge text and also says that she had told it to a few of her friends. I ask her if she could ask those friends if they told anyone and tell them to not tell it to everyone. ( I wanted to tell it the dude from earlier first before he hears it from someone different). She agrees and asks them but they haven't told anyone and they promised they wouldn't. The day after I tell the dude that i had feelings for her and he seems super cool about it, we at this point have a super long talk also about trust and that i would never and have never told her anything that he didn't want me to tell her, but then he says like "i also kinda knew about it" and something that I can't translate to english very well bit it is like "I heard it somewhere" and he also said: "but you don't have to tell her". So at this Situation I know that one of the girls closest friends lied to her and I tell her immediately after that he knew it from someone. Apparently she asked him immediately after that where he knew it from, and this is where he gets super angry at me because he had "clearly told me not to tell her"  so the "but you don't have to tell her" was a "don't tell her tho" but i didn't think of it as that.

so, people of reddit, Am I the asshole? and please not just about this last situation but about the whole story. Thank you for your time
