I told him I felt chemistry with him. He didn’t say anything but he grabbed my hand and squeezed it hard. Does this mean he feels it too?

It means he feels something whether or not it's the same as you only he knows but I'd say this.

It's most likely that his actions speak louder than his words so watch his actions. He might show you not through the big things but the tiny things, the things that most women never even notice because they are too busy looking for the grand gestures.

It may be that you tell him how you like your coffee only once but he remembers it and gets it right every time. It may be that he sees when your scared or unsure and he's there with a hug that tells you everything is going to be ok, it's these things men are good at but it's also these things most women don't see because they are looking elsewhere for the big things, the big declaration while most men are just busy already doing it through the small things
