Yes, it is true that some men will leave your message on read just to get you to constantly think about them.
It puts them in the power seat because they are then able to manipulate your emotions and have you constantly questioning whether they like you.
Your crush keeps leaving you on read because he knows that he is able to control his interaction with you and what you are thinking.
He is able to anticipate your actions.
If you want this to stop, you will have to give him the impression that he is not in control and thereby cannot anticipate your actions.
An effective way to do this is to stop reading his messages for a while. As tempting as it may be to do so, if you want to gain some control and have more of a balance of power in this interaction, you should avoid reading his messages.
Instead, engage in really fun activities with friends and new friends and post those experiences on your social media.
As he sees all the fun that you are having and the fact that you aren’t reading his messages, he will panic and start wondering if he is losing control.
This will most likely lead to him becoming a lot more attentive towards you and he will feel the need to prove that you are important to him by making sure that he not only reads your future messages to him but promptly responds.
