I have been away from which company for more than 4 months, and now I want to go back. What should I do if I send a text message to my boss and don't reply? Am I a bitch?

Be a man, be modest in everything, and don't know why you left your job. Personally, if you think this job is very important to you, you should go directly to him with a sincere attitude and let him see your sincerity. Everyone makes mistakes. It should be good if the boss understands that you will work there in the future. If the boss deliberately makes things difficult, it means that he is not broad-minded enough to leave, but first you must have a sincere attitude. I won't send you a text message to reply.
