Is it a waste of time trying to connect with my biological dad?

I (18F) don’t know if it’s a good idea trying to connect with my biological dad (42M). My mom and dad met in high school, dated, and got married right after their graduation. My mom gave birth to me and had really bad postpartum depression. My dad ended up leaving her (divorce) and she passed away. My dad raised me, kinda, but usually left me at my maternal grandma’s house. She’s more of a mom/parent to me than him.

Growing up, my dad would come around here and there. He stopped when he got remarried. His wife already had kids (who are older than me). He took on the dad role for them and I guess forgot about me. Now, we’ve been in contact with each other. He sometimes asks about my school life, friends, and about my mom’s side of the family. Now that he’s back, I wanted to know how to connect with him better. My grandma took on the ‘motherly’ role, but I didn’t have a father figure. I guess you can kinda count my uncles, but they were busy raising my cousins.

My dad’s the typical dad (likes to watch sports, drink, etc). Personally, what’s the best way to approach this? I want us to connect, and I do want a father/daughter relationship. (I’m guessing some people here are dad’s/parents themselves). 🙁
