We have been together for half a year. What do you mean when people say congratulations, but my boyfriend says there is no ambiguity?

It is obviously inappropriate to say this, because if you are together, if the other party says this, it is obviously a disrespect for you, almost a denial of you, so you are particularly humble in this case.

However, this may be just a social way for the other person. Sometimes the other person may be humble, but whether he is humble or not, he must give the other person a respect in front of his girlfriend at this time, because it is fair to both people. Only when he respects you will others respect him. He should understand this truth.

So, at this time, you can communicate with each other what kind of mentality the other person is, and clearly tell each other that if you are together, you will belittle yourself at the same time, because since you choose to be together, then you are a whole, with one glory and one loss.
