Your welcome i had feelings for him too and i still do, and he treats me like complete and utter shit, and i mean litterally, I know how your sister feels, he thinks little about the feelings of anyone else, he is actually trying to start a relationship with the guy i had something going on with, and ryan knew it, yet at the same time he is trying to have a relationship with the guy he made out with like 5 different people last night, and hit on a girl and made her feel so uncomfortable, he hits on everything he finds attractive, worese though, he leads people on, as he did with me and now you sister.
Just to let you know though, ryan is not an asshole nore a dick, and actually the whole dick thing is like an inside joke type thing between ryan and i, so i wasn't calling him a dick, but yeah what he did to your sister was completely wrong, he doesn't mean to hurt people, i truly do not believe he is out to intentionally hurt people, but he just does, please understand that him hurting your sister was completely unintentional and i am sure if he knew it would hurt her he wouldn't have done it, actually i promise if he knew or even had some small idea it would hurt your sister he wouldn't have done it, he just doesn't think of others most of the time, he as this idea that he is all that matters, he is most important, and it sometimes clouds his judgement and it makes him not think through his decisions and his actions. I am very sorry for what he did, but please understand it was not intentional. And if you or your sister ever need to talk to someone about him, about anything, i promise i will be there for you, both of you.
