The only one that can validate your relationship is you.

How to find the right person to start a relationship with you only you can answer.

I suggest:(lalala)

1. Get to know yourself as you actually are
People tend to work up fantasy scenarios of who they think they should be. The first step is to cut thru all those personal delusions you create to try to identify you. It takes self-honesty and self-realization. Making an opposing list helps sometimes.
List what you are (supported by reality) and then what you think you are (supported by fantasy or delusion).

2. Remove your compulsions rooted in delusion
Start with small things and work your way into the more difficult changes. This involves changing behavior to align with your true nature (that you established in step one).

Note: You will not be ready for step 3 until you complete the prior steps and become the person you actually are. By this time, you will understand your values and have control of your life. You will have gained emotional maturity.

3. Figure out what qualities you really want in a romantic partner (know what you want)
Be specific, but understand that flexibility is also important. Understand that no person on this planet is able to be exactly what you desire in all sense of the concept. Prioritize your list to qualities that enhance you and are compatible with your lifestyle and your desires

4. Start looking for potential matches as you move thru life
Look for matches everywhere you go, both online and real world.
Go places that are in alignment with your personality. Identify traits in those that interest you and when you find matches, step up and explore the possibility by getting to know that "person" better.

5. The "Date" is the first step, not the last
Understand that just finding your impression of a match and going on a 'date' with that person is not a goal but merely a beginning sequence to understand that person as that person is. It is your time together with them that establishes the romance. The compatibility of any relationship requires both parties to be in alignment.

You have to allow the other person to be themselves.
If them, being themselves, is what you desire
AND
You, being you, is what they desire
You have a chance to have a serious, meaningful and contented relationship.
How it progresses from there is entirely up to the two of you.

FFS, you're 18. Worry about school, a career, and the life you intend to lead. Meet people and enjoy the freedom of being young and unattached.

So am I.

I agree with you.

That is what makes it so exciting is the unknown
