My boyfriend always laughs at me.

First of all, I often laugh at my partner at home, haha, but do you know people's reaction? Laugh until you die, because she knows I just like Doby. It is not normal for her lovers to play jokes on each other. You can wait until you see what happens when others laugh at you. Don't hit him.

It should be your self-esteem, and when you laugh, your heart is weak, and you are not sure what he is laughing at.

Don't take face too seriously in front of couples, it will be a lot less fun.

hope this helps
