3. They can never make you happy
No one can ever make you happy; you have to be happy with yourself first. That being said, if you felt anxious, sad or unimportant around someone it’s a good reason to break things off with them. You shouldn’t have to be with someone who puts you down, belittles you or treats you like a last-minute option. A healthy relationship should bring joy to both people involved, rather than making you feel like you are better off alone.
