How long is it ok to not be in a relationship?

Check out San Francisco. Being the only heterosexual male in that place always works...

Small talk and coffee are great ways to begin. If a girl in your class interests you, find something that happened in class to speak to discuss with her.

Big Tip: Do your reading and contribute to the discussion. You should get a favorable rating.

Bear in mind that the fear-based aversion
becomes more intense, the closer to the chick u get
and the further u run away from her, the more attractive
she gets in your mind, and the more self-confident u become
until u get back to the point in the cycle when u approach again
when the fear-based avoidance re-intensifies.

Tell your mother you're looking for a girl just as wonderful as she is, but they are SO rare.

so an example would be:
i see this girl i'm attracted to on the first day of class. as the semester goes on i try to chip away at getting to know her and i start to become more and more interested in her. then once i feel like i have her interested in me or i know for a fact she is, i pull away. i start to find little things about her that i don't like and use them as excuses. she also doesn't seem as attractive on a physical and or personality level anymore

cause that has happened before, more then once
i never really noticed that until know, if that is what you're talking about

wow

A few things:

Does your health insurance cover counseling? If so, you might try it.

Perhaps, you are not ready for a relationship or you have other underlying issues you have not dealt with. See above.

Remember, worrying about anything often makes it worse.

Finally, there is no "rule" that says everyone must be in a relationship.

No; u keep chickening out,
as u approach her to ask her out.

If you develop certain relationship-unfriendly hobbies such as becoming a full time trekkie, you can anticipate being single for the rest of your life; whether or not that's ok and whether or not you're happy that way depends largely upon you and your attitudes. But if you're happy and not hurting anyone, there's no reason not to enjoy the single life.
