I think feelings just "are". They're information to you about yourself as you are relating to your surroundings. I think they're only "wrong" when one gets one's head in the mix so one makes judgments based on them about other people. Feeling someone doesn't like you doesn't mean they don't like you! Feelings are yours and only tell you about yourself, not about what other people are actually feeling or thinking, you have to ask/confirm with other people what they are feeling or thinking.

However, that doesn't mean that your sense of whether the other person is "good" for you is "wrong". It is that sense they do/do not "like" you, which is actually your sense of whether you want to be around them, not whether you like/dislike them (you probably don't know them yet) but whether you personally are comfortable around them. No one really likes to think/feel they are rejecting another so it is easier to accent the feeling that the other person doesn't "like" you than to realize that you don't like the way you are feeling around the other person and either try to resolve it (ask the other person how they are feeling and try to get to know the other person) or "accept" one's feeling as one's own and move on.
