Here are some things you can consider to help you decide if your partner is "the one" :
- Do you live together?
- How long have you been together?
- Has he met your parents yet?
- Does your partner have similar goals and dreams to yours?
- Do you believe in love at first sight?
- Does he make you feel safe?
- Does he make you feel wanted?
- Does he make you feel good about your life and future?
- Does he make you a better person?
- Do your friends and family affirm him?
- Does he make you feel like the one?
- Does he make you part of his life?
- Do you picture a future with him?
- Do you feel safe and calm in his presence?
- Do you share everything?
- Are you not afraid to show your true self?
- Is he willing to talk through conflicts?
- Does he want to strengthen your connection?
- Does he not try to change you?
- Does he not always tell you what you want to hear?

I hope this helps! Let me know if there's anything else I can help with.
