What does it mean when someone says we have chemistry?

According to me mam, I think it means that he feels there is a connection or he thinks that he is compatible with her.
By which I mean he feels comfortable around her and they have some similar likes and dislikes.

means they're in love and keep each other happy and understand them well and they as some may call it 'click well', emotionally and physically , and hardly ever argue , like there's disagreement but not rguments

Either he's saying it's easy being with you (he doesn't have to stress and can just enjoy your company) or he's feeding you a line because he thinks it's what you want to hear.

You'll know after a short while which one it is.
