How can we understand that we are loved?

I wanted this post to be a little different. Usually I ask myself, I answer myself again. However, this time I want to learn your answers. My question is:

How do you know if a person loves you?

I just want to give 3 of my own answers.

1) I feel his love when he looks at me.

2) He is polite and courteous when talking to me.

3) He calls or texts me when I'm not with him.

I didn't think too much about this topic. Obviously I want to know what your opinions are on this subject. "Reason is superior to reason." they say. I got great comments in my other posts that I had never thought of. This showed me how valuable your great thoughts and ideas are on these issues, instead of finding every result, solution, and idea myself.

I would be glad if you express your valuable thoughts in the comments.
