My boyfriend joked that if I had an affair with someone else, I would kill the man and me. What is the reason?

I don't think there is anything to be afraid of. I once said the same thing as your boyfriend. Hehe, really, it's just that I'm a woman. I think it's nothing. It just means that he likes you and cares too much about you. And I think both men and women are possessive, that's for sure. Do you want to care about your boyfriend with other women? Do you want him to have two girlfriends at the same time

If you think your boyfriend is uncomfortable, instead of thinking about how much he likes you, I don't think you love you as much as your boyfriend.
