Dream

Butter asked 10 months ago

I am together with him for 6 years now. We start living together for almost 2 years. He’s a nice and good person, family oriental, funny, etc.
So, I dream about him cheating on me last night. When I woke up, I told him about the dream while crying. He told me that it’ll only happen if I don’t take a good care of him. As if trying to convince me that it’ll happen anyway. I asked him why would he say that when I do take good care of him. He said that he want to make me scared of losing him and says it was only a joke. I told him that I do not like to be played around when I am seriously talking and sad about something. Then, he told me that I take things too seriously and make everything’s a big deal. 
Now I am not sad about the dream. But the response of I am getting out from him. When I told him that he couldn’t pick a suitable time and situation to joke around, he responded that he wanted to go back to sleep instead.
Therefore, I feel like he is ignoring my feelings and shows no care at all about how he handles the reality with me. At this point, I don’t feel like I am important to him.
I need an advice for this. Is he right? Was I make everything’s a big deal? How do I make him understand about his communication problem? Am I suppose to think I should be taken seriously?
Anything.. Would be nice to know of other’s opinions.
Thank You
