Love yourself- is wrong or you always need someone to be loved?

I don’t understand why people want to see you in a relation, is it required to always have someone. As per my perception it’s not true, can’t you love yourself only? I remember a few months before, I had a conversation with my friend and she asked me about the same question and I said, I don’t want anyone in my life. She didn’t understand why I have said that and she asked me, am I scared to have someone in my life or someone was there who cheated on me, and my reply was very normal. There was nothing like that my dear, I love myself and have found love inside me, and in my surroundings so never felt to have someone or need of someone to love me. She was quite surprised with my answer and retaliated back just in a second. I knew it was not easy for her to give consent to my opinion as I thought it was a kind of comment, is everything okay with me, or am I homosexual or something like that. For a few seconds I was shocked, we both looked at each other, and after that I started laughing.  It was out of head for a moment, I was not angry with her at all because I knew she was my friend; it was just a joke from her part she didn’t have any wrong intention, and she never wanted to characterize me. But later I have realized the depth of this topic, how many people are having the same problem. They are forced to face this kind of question because they just love themselves. Why sometimes we have to face social obligation, Is it a kind of sin to live for your own dreams?  I know this is not true for every part of the world, where people don’t bother about others but true for those, where people are still trapped in some old traditions.
