Is texting back together harassment?

There is no absolute answer to this question, because everyone's situation and feelings may be different.

Generally speaking, sending him a message of 1-2 every day is not necessarily entangled, it depends on the specific situation. If you send him a message just to share your daily life or communicate, it may not be entangled. But if you send him a message mainly to save feelings or ask for reunion, and the other party's response is not positive, it may be regarded as entanglement. So you need to carefully consider your own motivation and the other person's reaction to judge whether it is appropriate.

In addition, it should be noted that even if you send him a message, it is not entangled. If the other party's response is not positive or has made it clear that you don't want to contact again, then you should respect the other party's decision. If the other person has lost interest in you, then you need to accept this fact and try to learn and grow from this experience.
