Does anyone else find it hard to connect with anyone even though you are social

I just noticed this about myself that I can not connect anyone unless they want the connection. For example, I was eating with a group of students. I thought I was connecting because I dont have a problem leading or speaking up however when one of the students decided to not come to lunch, I realized how much I was riding the energy of others.

Me and the other student just sat in silence. When I did try to bring up a topic, it lasted maybe for a minute or two. He wanted to talk to me as well but its like we couldnt connect. Then out of nowhere we started talking about our future. IDK how it happened but it got more deep and the convo was more serious.

Another guy showed up and it went back to being fun. This example has been happening with everyone unless someone likes being in deep convos.

How do I fix this? I want friends and I am struggling with this.
