My son wants to meet me

When I was 16 I was assaulted and it resulted in pregnancy, I had him when I turned 17 (I am now 27) and I guess he’s at the age where he’s asking about me and saying he wants to meet me. I am MORE than happy to see him again, but now that he’s 10, I don’t really know what I’m supposed to say or how I’m supposed to interact. He lives in a different state as I moved out of state 5 years ago, and I haven’t seen him since he was 2. I used to see him fairly frequently but then that dwindled down and i don’t know if life just got busy or what, but my parents have stayed in touch and see him quite often now as well.

Really just looking for advice on… potential questions I may be asked, how to interact, etc etc. I’m so so nervous.
