Is he cheating?

My boyfriend and I saw eachother at the mall the other day. my cousin took me to see him. im not allowed to seee him because my parents told me not to. so after we got back from the mall, he told me that if my parents don’t agree to letting me see him then he is going to leave me. now the other day, he said the same thing that he was going to leave me if my parentss said no.. then he changed his mind and said he would be with me forever and never leave me. so he has changed his mind about that subject 4 times now. anyway, he said he didn’t like the way I was acting at the mall yesterday and said I was acting like my cousin was my mommy?!!! I was hugging him the whole time and telling him I loved him, and he said I treated him like s*it?? so then he basically broke up with me, with no emotion at all. then he decided to change his mind again. now were going to wait to talk to my parents. basically he second guesses me a lot. My cousin htinks hes got another girl and is confused of what he wants. please could someone give me their input… Im so confused and really stressed now. I’ve lost alotta weight through htis whole thing… Please help
