<human>: Provide a brief overview of the text.

Our relationship was great at the beginning, but after being together for 5 years and living together for 4 of those years, she told me last week that she'll be moving in with her parents, leaving me, and taking our dog.

The breakup was a bit emotional, but it wasn't a big shock. I have felt us drift apart for the last year or two and she no longer gave me any affection or really tried to work on the relationship. It felt like I was just living with a female roommate that would occasionally have sex with me if I asked nicely.

In the last few days, I've browsed through profiles of local girls on a couple of dating sites without signing up. At first I was disappointed and felt like absolutely none of them in my city were even close to what I was looking for until I found this one.... she was different.

Now I've kind of become obsessed with her profile and feel like she is exactly my type and I'm probably hers. I just don't know what to do now though...

I am pretty much over my ex because it didn't even feel like a relationship for the last year or two, but I really don't know if I should start talking to new people already or not.

Now that I'm single and vulnerable to the possibility of rejection, I am starting to be self conscious about my imperfections again.

Should I sign up for this dating site and message this new girl before someone else takes her off the market? Or do I need to just chill out for a minute and work on improving myself first? Am I setting myself up for failure by putting all of my eggs into one basket with this girl?

I haven't really been single since I was a teenage virgin so I'm lost and could use some advice...
<bot>: My long-term GF broke up with me a week ago after our relationship had drifted apart for the last year or two. I found a girl on an online dating site that seems perfect. WTF should I do?
