Communication is a skill (& a hard one to learn at that). I know this, because I am still in the process of learning how to communicate & do it effectively thus getting the responses I want myself. I too am very afraid of being rejected, & hated & thought of as annoying. I suppose that to others, you may come across as an asshole, but I don't think you really mean it. However, it's likely that other people who have talked to you think that you are because of the way that you present yourself in order to avoid being rejected & hated, etc. Hope this helps,
