You can do all you can think of to be kind and supportive to another and it the truth is that no matter what you do, some people simply won't like you. You will be all the wrong person for them--it might be the way you use words, the way you look, your interests, your profession, your politics, your values and beliefs, your family or more. You may even be unattractive to groups of people who share similar traits--a type of people that simply finds someone like you distasteful.
What do you do when that happens?
First, acknowledge the pain in this. While it is certain that some people won't like you in life, it is painful when people close to you don't like you. That happens for all kinds of reasons. I remember a situation like this in a professional sphere I worked in long ago. My age, history, and outlook on life were so different from that of another--she simply had no understanding, interest, or acceptance of who I was. I never really understood why, but I simply accepted that was the way it was. The person was respectful and not harmful. We peacefully coexisted with this reality, but I would have preferred a more positive professional working relationship.
Next, look for the truth in the situation. Why is this happening? Is there anything you can do to make positive change?
After that, be respectful of the individuals, but keep your distance. If you've been warned by words or actions, it's best to stay away. Why make things worse? Seek places where you are respected and embraced instead.
No one has the monopoly on what is right and what is wrong. There are many, many ways to live life, and in my opinion, what's important is that we each seek to live our truth without harming or hurting another. That's important to me. Onward.
