For your sake, you can tell her that if I call you or send you a message, you must remember to reply to me. No matter how busy you are, even if you reply me with a "busy" message, although I know it is perfunctory, it can also alleviate my concern for you a little.
On your own side, you should restrain yourself and not be too persistent (comfort yourself, even if she leaves, there will be something better)
Men should remember not to be cold and hot to people, which will make you immature and many people will not accept it.
Another way is to get into the habit of calling her. For example, when you just get off work, you can ask her if she is tired after a day's work (that is, if you want to talk to her more, she may be wronged or unhappy, and then comfort her as a boyfriend and give her encouragement. PS: No wonder. If the person closest to you doesn't support her, then she will be very sad. Even if she is wrong, don't say it then. In fact, it doesn't matter whether you say it or not, it has nothing to do with you. What happened in her work has nothing to do with you. Why tell her the truth? You just need to love the woman you need to love. )
Some things, others say, are suggestions. I just hope I can help you.
