The boy said not to text him again.

If your ex-boyfriend makes it clear that he doesn't want to hear from you again, it may mean that he wants to keep his distance and start a new life. In this case, it may be the best choice to respect his decision and give him some space.

Although you may feel disappointed and sad, you should also realize that everyone has their own boundaries and needs, and your ex-boyfriend may just want to keep his distance from you. If you really want to give him a chance, you can wait a while, give him some space, and then try to communicate with him to see if there is any chance to re-establish contact.

However, it should be noted that if your ex-boyfriend has made it clear that he doesn't want to contact you again, then you should respect his decision, stop sending him messages and try to contact him again. Too much contact may make him feel troubled and stressed, which will make the situation more complicated and difficult.
