OK. I have some thoughts on this.
1. People are allowed not to like you, or even to dislike you.
2. If you ask people specifically if they do not like you, you should be prepared for an honest reply. If you may a have a problem with their answer, don't ask.
3. If you ask people about why they dislike you, you should be prepared not to like their reasons, but it might be even more helpful to be open to accepting their reasons and examine in yourself WHY they reply the way they do, instead of just saying they are wrong.
4. What is the point of asking if you are simply going to dismiss what they say as wrong, and not use it for personal growth?

Good Luck.
