Re: If someone doesn’t like you…
I think it depends not only on you but how your decision will effect others.
i.e It could be case where you r single and other person is single. I would walk away.
second case could be… If you are married and that person who doesn’t like you is important to your spouse, i will make an effort for person to like me and if there is no improvement at least i can be satisfied that i made an effort.
third case could be. If you have children and your spouse ended up not liking you anymore, i will make an effort for person to like me for the sake of kids. Again best one can do is try and if doesn’t work out, ohh well !
