How do u know that the other person u like is ur sole mate. Is fairly simple exept it’s not. It’s hard to find the other half. That’s why you date and try to find that other half. Not all people have but don’t freak out there is one out there. How do u know he/she is right for u or is ur sole mate well when u can look at them and smile for no reason and they can make u smile just by saying one little word or when u know everything about them without them telling u or when u can talk to them though ur mind. That’s only a few way to relies someone might be ur sole mate. Remember there is someone out there for everyone u just have to find them.
