My boyfriend always says that I am fat and want to lose weight. Is he really joking or serious?

My object is152kg. I never said she was fat, but she always thought she was fat or something. I love her very much, and I really don't care if she gets fat. As long as she is healthy, I will say that every time she doesn't eat and lose weight, I will say that she really doesn't care about her figure. This only shows that your boyfriend is not mature enough. Maybe he is really joking, but he knows it.
