<human>: Give me the gist of the text in a nutshell

Hi all,

I just thought id take the time to ask a few questions for those who may help me find direction now that I am single. I have been in a number of 6-12 month relationships over the years, all of which have happened very soon after one another - yet were obviously unsuccessful. Now that I am again single, i find myself automatically wanting to find another person to date.

Is this normal? I am having a hard time accepting myself as single and being happy with this. I know that friends are important, and that you have to be happy alone to be happy. With all of this in mind, its just not happening. I am attempting to focus on my fitness and work currently, which is fulfilling somewhat - but its just not helping me when late at night ... theres just nothing to do/noone to miss you or really care about your day. 

My friends are all ok, they are good enough company - but its a different sort of company as you know you are just a part of their life - you are not a foundation for it.

I'd like any comments, and suggestions on how I can better myself and stop caring and wanting more for now. Even my friendships i easily ruin by letting myself feel too much, or we get physical and then its just awkward. 

*there is not even anyone currently who i wish i could be with, I miss my ex's because it was a relationship where I meant something to someone - but i have no intention of ever going back....but at the same time I find myself on all the dating sites and apps. The guy I am sort of "seeing" doesn't seem as keen as I am - and so I just hope to gain some insight on how to better myself...I just want to be happy.
<bot>: I am not happy alone, and wish to find out if this is normal or if it is purely something time will help me push away.
