<human>: Can you summarize the given text in a few sentences?

Before and directly after my past girlfriend, I wasn't great at being alone. I pretty much always had to occupy myself with doing stuff, and if I was left alone, it would very quickly get me down.

I moved to a new city though, and as I got over my ex, started dating other girls. I got over a lot of my issues and despite living with a good friend of mine, I actually started to look forward to the times I could spend alone, even thinking that one day I might actually like to live alone. 

Anyway, fast forward to a few weeks ago, I started dating someone new. We haven't even had sex yet, but I already feel a very strong connection with her, stronger than anyone that I've been dating over the past few months. And the worst part about it is that I'm starting to get back those old feelings of not liking being alone once more and I really don't like it.

Does anyone have any advice beyond just make yourself busy?? I would really like to perhaps identify the route cause of the problem instead so that I can really fix the problem.
