How to answer the sentence "I seem to have gained weight" said by my girlfriend?

When falling in love, boys may often hear such complaints from their girlfriends. However, do you really have something to say about these complaints? In fact, if they are related to figure and appearance, people who say them will have a slightly different mood. If a person finds himself fat, he will inevitably worry about how the other person will feel about his harvest before meeting his long-lost friend. Therefore, some people will laugh at themselves first, point out their most obvious changes first, and reduce the possibility of hearing from others that you seem to be fat, so as not to get hurt inside. This kind of person will feel inferior and uneasy about his physical changes, and at the same time care about what others think of him. Sometimes, because they don't understand each other's feelings, the worried party will be more uneasy. Therefore, in order to get rid of this anxiety, some people will preemptively confess what makes them uneasy, which is equivalent to directly revealing their inner feelings and giving the power of judgment to each other, which is in a very fragile position. If the other person is outspoken, it may make her depressed all day.
