1. Although we do not deny that there are normal friendships between men and women, this society is really a generation with too many temptations and unpredictable people. Your worries are justified!
2. But the other side of the problem is your girlfriend. Her heart is very important. Maybe even she herself can’t understand how she feels at this time; she should learn to respect you first (if you are If you are in a relationship!), she is no longer a child. She should learn to deal with this kind of emotional problem, express that she cares about you, or learn to express in front of that classmate that she already has a boyfriend she likes; or in disguise in front of the classmate Contacting you on the phone shows the love between you and makes the other party aware of your interests. If your classmates’ intentions are not pure, they should express it more directly!
3. If your girlfriend is the type who is not very good at "hurting" people, you may have to "work hard" (I hope she makes you "uncomfortable" just this time, never This is the case for many people, because it is not a good habit!) If this is the case, you need to have "full" communication with your girlfriend, and it is recommended that you take the initiative to contact her classmates when necessary, and pay attention to your words. Provocation is an expression of willingness to make friends: "Since you are my girlfriend's friend, you are also my friend..." Your "boldness" may make the other party give up. If your girlfriend really loves you, and because of difficulty, If you retreat and are in trouble, I will be very grateful to you! (The premise is that she really cares about you)
My best wishes to young people: lovers will eventually get married and have less such worries...
