what do u do when ur in love but can't be in a relationship?

What's a girl supposed to do when she falls deep in love but knows she cannot be in a relationship?
How does a girl deal w/her feelings for a guy when she knows she cannot tell him?
What does she do when she is terrified of sex which is linked to her fear of pregnancy?
She knows she cannot have an abstinent relationship,but she is so madly; so DEEPLY in love w/this man, it's crushing her.
Her feelings grow stronger everyday; by leaps and bounds every second of the day, yet
she is terrified of having sex and knows that she will one day, have to have it in order to have the guy.
It isn't fair.
She wants to stay away from relationships because of this,but she is just too deep in love to avoid it.
Her fear has a death grip on her.
She knows of the consequences sex brings,and knows that she does not want it.
She also knows that a man she does not give it up to,will not stick around.
She is frustrated and ready to cry; ready to scream.
She has come so close to getting her guy.
She can tell he likes her too(she thinks),but she is even more sure that he will not put up w/her being the way she is.
She's so deep in love, it hurts.
But her fear is so strong, and that ALSO hurts.
She wonders if she will have to let him go to keep from going through the same stress and heartache she went through w/another.
But the thought of not having him breaks her heart into a million pieces, yet
the thought of having sex scares the living daylights out of her.
What is wrong w/her?
She knows why she does not want it, yet
is it NORMAL to feel this strongly about it?
Is it NORMAL to be FEARFUL of the act in question?
She beats her head against the wall; she has constant self conflict.
She does not tell him she loves him not out of shyness,
nore out of fear of rejection,
but out of fear she'll have to lie down to get him and keep him.
It makes her so scared.
like having to relive the same nightmare as last time only with a different guy.
She's frustrated.
She's depressed.
She wants to hang onto her virginity,but
she also wants her 1 true love.
It isn't FAIR!
The constant self battles of having to choose:
her virginity or her 1 true love.
Why can't she have both??
Because this is the real world. that's y! she KNOWS she cannot have things her way.
This is not a fairy tale!
This is real life.
HER real life.
She knows she will be forced to leave her comfort zone, or risk losing a wonderful guy.
It isn't fair.
She just wants to scream.
She just wants to cry.
She just wants to die,so it won't even be an issue.
Why can't this be..maybe not easy,but painless?
