So I've been dreaming of my ex. Some
Back story. 

I've known her 3 years and we have dated twice in that period. We started dating again when we meet each other at clubbing, hooked up and spoke the next day. So she walks away again and we keep talking to try and work things out for a third time.  

We fought heaps, never saw each other  despite how much I tried to see her and I also told her I needed to see her more. So nothing changes and then she does something so I have had enough, I'm done. 

Don't get my wrong I love her so much, I always will. She was my first love, virgin before her Etc. so I know even though I love her more then anything we aren't meant for each other. It just won't work. I can't say I miss her because, what do I have to miss? Nothing positive came out of dating her or her being in my life in the last 6 months that I couldn't get from a friend.

I haven't texted her to just tell her I sent her a letter to her house but forgot to write the name in it. Just an apology for everything and I hope she finds someone to make her happy and that can understand her like I couldn't, that I love her, I won't forget her and if she ever needs someone ill be there for her (she doesn't have a lot of friends as is very depressed with her father over seas for military). 

So I don't miss her, When I think of her I just tell myself. Hey she wasn't good for you, the relationship never fulfilled your needs and return to what I was doing. I joined gym, love it. 

So to the point, I find myself dreaming of her, I wake up after its over(I only ever do that with nightmares). It's just situations and what not. 

Can anyone offer me some insight on why this is? I don't understand I guess.
<bot>: dreaming of my ex girlfriend I recently decided its time to move on. I don't miss her, she wasn't right for me. Looking for any insight.
