This morning, while my boyfriend smoking. It smelly and made me coughing. After finished my bathing, I said to him " When you stop smoking ? You never try to stop it, after I stop talking about it you smoke more. Would you stop smoke or stop our relationship ? I am seriously now. " Even though I am still stand my words, but I don't force him much. I know it's not easy, but it'a good for his health for rest of life
