<human>: Can you give me the gist of the text in a nutshell?

I like to think that I am over my ex-girlfriend, but something remains behind inside of me.  I am constantly thinking about her and I don't know what to do about ridding these thoughts from my mind.  I ended things with her, on my terms.

I can't seem to figure out what it is that I miss.  Is it her and all of the good memories we had together, is it the physical presence that I miss, or is it the intimacy we had together?  

Her previous bf kinda stalked her/creeped her out after they broke up and was trying so hard to get back together with her after they broke up.  Since I cut ties with her I don't think I've really contacted her at all, because I don't want to be like him and I'm also not like him at all.

I want to txt her/contact her, but I don't know what I would say or even where to begin.  She had a boyfriend less than a month after we broke up, which is fine because we are no longer dating and she can make her own decisions.
<bot>: I want to txt my ex, but idk if it is a good idea/do I miss her(physical presence) or do I miss everything we did together(sexual and non-sexual)?
