What to do about my boyfriend?

my boyfriend and i have been together for 10 1/2 months and recently he called my 9 yr old son something i didnt approve of. we have got to the point we dont really talk anymore and also he had started treating me like im stupid or something. i almost left him a few weeks ago but its almost like the lord made me see that i was sad for not only me but for him as well. i dont know what to do. i dont know what to say to him. i want us to work things out but he acts like he doesnt care. he said he loves me no less… someone wanna talk with me about this.
