How long have you and the other girl been seperated? You may still need time to move on...

It has been a while. And she also has a boyfriend. I am really trying to get her back. but I don't know how. I am just so sick of feeling this way you know?

Clearly you arenot over her. You still have strong feelings for her, and guess what? That means you are a good guy. Because you don't see yourself having sex with or desire other women because of the feelings you have for the one girl. That means that when you're in love you're capable of being monogomous. I say that's great.

I say it's depressing because it hurts so much to be without her. I have never been so weak about something before. She is someone I look up to and admire. We had such a nice this going and I ruined it. I ruined it all.

Well it sounds to me that sex actually means something to you. I'd say don't push for a sex life for the wrong reasons.
In terms of this girl, don't blame yourself for it. It seems like it's over and it's time to try to move on, although no one said that would be easy. Yes, she was important to you, and I'm sure you can take something positive away from that, but there will always be other girls. No, they won't be exactly like her, but really think of yourself a year or two from now. I hate ending relationships too. I'm around to chat about it if you'd like to.

I think its really amazing what your doing and maybe you should tell this girl how stronglyou feel about her.

It's just really difficult. She is so beautiful, but that dosn't define her. She is such a great person, She gets along with everyone, She is there when I need her the most. She gives me a hug when I am not feeling good. and I love the way her smile lights up when I surprize her with a bouquet of flowers. It's hard to let her go when I think of my future she is the main part. I feel so lost without her.
