Leo, your ego may be too big to let you start a serious relationship now
Your intensity on many occasions is quite intimidating, even intimidating yourself. You love it so much that it can scare you. Your inner strength and your self-love are not to everyone's liking, but you are already tired of having to please everyone.
You hate that they begin to draw defects that are virtues for you, and now you do not want to face that.
You do not want to start a serious relationship because you think you have not yet found someone capable of understanding you and your ego.
Leo, although you love and are in love, you often do not understand why it is necessary to seal love with a commitment when you can enjoy love, whatever it is, without labels or anything that says the love will be forever.
Love lasts as long as it has to, which doesn't worry or overwhelm you.
It is clear that you do not like to lose the person you are in love with, but what worries you now is living in the present and not worrying so much about the future. It is not that commitment overwhelms you; it is not necessary many times if love is involved.
If you don't want to start a serious relationship, it's because now you don't want to lock yourself up again.
You are a person who likes to go out, meet new people, start a conversation with someone you have just met ...
When you are in a relationship, it is possible that the other person is somewhat jealous and does not let you enjoy all that. Therefore, you save yourself all the misunderstandings by not having any relationship. Also, you don't know where the love of your life may be, so you don't want to close any doors. You don't want to commit to anyone for fear of losing someone else who is still out there waiting for you.
