<human>: This was my first and really only relationship. Obviously, We've been together since 18, so I have never been single in my adult life. To be honest, it sucks. 

I needed to end it because her life was going in a different direction than mine and her career would force her to move around the country every 4 years or so for the foreseeable future. Due to the moving, I have not had a chance to really develop a career of my own, but I've found jobs that pay ok. 

We broke up about a month ago and I have not spoken with her since. I moved across the country back to where I grew up and where my family is. I don't hate her, but she was pretty resentful that I needed to do this for me. In fact, to an extent, I still love her, but her career is her number one goal; which is why I didn't try to force her to settle down somewhere we both agreed upon.  

This has been extremely difficult for me. I kind of want to find someone else, at least as a distraction, for the time being. But the thought of 'hooking up' with someone and even dating makes me sick to my stomach. And even though we're not together, it still almost feels like a betrayal to look for someone else. 

So I guess my question is for those who have been in similar situations, how long did you wait before starting a new relationship after ending a long term one?

Can you give me the gist of the text in a nutshell?
<bot>: Have been with the same girl my entire adult life. Needed to end it. Now I have no idea what to do. Feeling completely lost.
