What to care about?

Well lately "Matty" has been lying to me about drinking because he know that I care and he knows that I will react. I do care about him and I dont want him to get in more trouble but how am going to care when he just wants to get a reaction out of me. Then he tells me that he cares when I try to talk to him about my problems but then he uses the words like "cool" and "nice". To me that suggests that you are getting annoyed about me...I ask if you are but the answer is always no. I want to think that you really care..but sometimes I think you just judge me...I dont know what to think anymore. I will always care but will you?
