Tell me how to judge whether a boy is seeing someone.

Beat about the bush method

You can praise him for anything at first, such as the lunch he brought at noon, and say, "Great, bringing home food, my girlfriend is so virtuous." If he doesn't have a girlfriend, he will definitely say, "Mom prepared it. I don't have a girlfriend." Or, you can point to his shirt and say, "This dress really looks good on you. It seems that your girlfriend has good taste." If not, he will tell you: he bought it himself, and he doesn't have a girlfriend or something.

Pretend to misunderstand

The specific operation of this method is to find an opportunity, for example, to give him two tickets, or something that couples use together or girls use. Pretend to say casually, "Oh, I bought it wrong. It's really a waste to leave it idle. Give it to your girlfriend." If he doesn't, he will immediately tell you, "I don't have a girlfriend." At this time, you can say, "Hey, last time I heard that you had a girlfriend, you've been dating for a long time. Am I mistaken?"? Ah, I must be mistaken.

asking questions casually

For example, a weekend or a holiday, you can pretend to ask casually, how do you spend this weekend? With your girlfriend? Next, let's see how the other person answers! If not, maybe you can just have a first date.
