My boyfriend asked me not to send him messages these two days for fear of getting me into trouble.

Your boyfriend's behavior is so abnormal because he is with his ex-girlfriend now, and her ex-girlfriend can borrow money from him, which shows that their relationship has always been there, and you are just a substitute. He also asked you to stop sending messages to disturb others, indicating that he was afraid that his ex-girlfriend would know about your existence, indicating that he was still thinking about his ex-girlfriend.

Of course, there is another situation, that is, your boyfriend owes a lot of money outside and then others find him. He doesn't want to involve you, so he asks you not to send him any more messages, because he is afraid that after you send him messages, others will see his news and harass you.
