Forcing to have sex instead of spending time w our son

I’m a single mom since last year. But my ex forcé me to have sex and that he will give me the money of my son. Have child support case pending because they are transferring the case from other state to where I moved. And my ex is giving me money using his bank check to get prove that he is paying child support so he doesn’t have to pay back when we have the court date. Well the problem is that he force me to have sex and that he will give me the money. Also he told me he want to make me pregnant but I don’t want go back with him. With this virus I cannot go back w my family so have to wait. But I cannot stand my ex cause he just want me to have sex instead of spending time with my son. I’m from Louisiana and my family is from Texas. Any suggestions what should I do?!
