How to send a text message to a long-lost ex-boyfriend? I really think I can't let go of this relationship, but it's unrealistic. Now I send a text message to ask him how he is.

Three months, no matter how long. Emotional things can be forgotten without saying forget. I advise you not to send this message. When I broke up with my ex-girlfriend, she brought it up. I feel confused and hold the possibility of feelings around us for the second time. It took me two years to forget this feeling that I still have illusions. So when a boy really likes you, he will insist and it will be hard to forget. Of course, I don't know what kind of person your ex-boyfriend is, but from what you said, I can see that he really likes you, so one of your short messages is likely to make him feel that you are giving him hope, so I don't suggest you send him a short message.
