First time talking to my father ever

Hello I am 19 I talked to my father for the first time ever. I found my father on facebook and got his number from my brother I met for the 1st time to off instagram. After my father left my mother he moved to Florida and started a new life. He remarried 3 years after he moved there and had 2 more kids. He plans on me going to florida to visit him and make up for the 19 years of my life he missed in a few months.
