Okay so, this sounds a lot like me a few years ago. I'm going to give you some things I learned. They may be applicable, they may not be. I have no doubt this chick isn't perfect but she clearly gives a fuck about you.

First of all man, sit yourself down and ask yourself what you want. Again this is what happened to me but basically I wanted her, her attention, her to be mine, and her when she is happy but she isn't going to be too happy, when that is all I want. You are treating her like an extension of yourself rather then caring about what is between you.

I lost her. It isn't, "the one who got away" because that concept does not make sense but I certainty lost her. She could have been a long term partner, easily. So maybe this chick is not for you or maybe you are taking a few things for granted. Looking through your own eyes a little too much.

Ask her, why does she feel that way? Why is she feeling "moody" (by the way, I suggest you update your language. Crazy, mood swings, insane, aren't going to get you far and only demean your partner). When something isn't going your way, don't think you're automatically right either. Emotions come from somewhere and if she is being emotional, she could be trying to tell you something. Listen. Don't just talk for the sake of defending yourself. Think. Digest. Consider them.

I'm never the one to start with the attitude but always the one accused of it.

This could be true but chances are, if your partner is trying to tell you something- there is substance behind it.

You're so affectionate with me it's annoying You're taking love for granted.

You always tell me you're gonna leave me alone and lonely and sometimes I honestly wish you just would.

If she wants to leave, let her leave. Sounds like she doesn't yet but if this communication keeps up, she probably will and it won't be pleasant.

You aren't me and there are a lot more things to be said but if she was anything like her, her head is in the future. You are in her future. If you are acting non favorably short term, how can she keep up the long term vision? Why would she, when you said yourself, she can do better in the short term then you.

Look, she might not be the one for you and that is okay. If she wants to walk away, let her go. If she has walked away already and is gone, learn. If you feel she is leaving, ask her to stay. Ask her to do nothing but listen to you. Talk man. Just fucking talk. Be vunerable. If she does not listen, so the fuck what? She obviously isn't the one for you.

Also, another thing I did, don't ask them to sit around waiting for you to speak. I kept telling her to wait until I got my thoughts together or the moment was right. I was so fucking angry for years when she got up and left. I sounded a lot like you.

There will never be a right moment. They just happen. You should always be thankful of those you love and love you, otherwise you take them for granted and lose the things you didn't know you had. Not telling you to fix things with her or that she might be someone you should fix things for but just consider. Consider and think a bit more.
