Why would my ex call me after 2 years of no contact?

Anonymous
We were each other's "first loves"- so I was crazy about the guy. We were in a long distance relatioship. I had to break up with him cause he'd flirt with girls on Facebook even after I confronted him about it and I couldn't handle it. He never tried to beg me to stay or whatever, he was chilled about the break up and I was shattered, that's when I got close with my current boyfriend.

I broke up with him just over two years ago. I had told him I needed to end all contact with him in order for me to be able to heal and move on, so after blocking him and deleting him off social networks, I never saw the need to talk to him again. That helped a lot cause I'm with this amazing guy now and we're in love and everything is perfect (it's scary).

Now, after 2 years he calls and asks how I am. :/
He seemed to know where I stay (we now stay in the same city) and where I work even though I never posted such on my Facebook or anywhere else- I guess he asked our mutual friend cause he got my contact number from her.

The conversation was awkward, why would an ex contact you after 2 years of no contact
