This is not good

I Like my boyfriend very much, we just got back together 4 months ago but I don't know if I am happy or not happy? Let's say this, I go to work, I'm relaxed, I get off work, he calls and right away it's going to an argument. He says it's me, (I over think) we argue almost everyday. I think it's because of me over thinking but the reason I over think is well, (I caught my boyfriend watching porn) - gets me to think maybe I am not all he needs even tho he says I am everything to him.

What do I do? I know this sounds maybe over rated with excessive negativity.

What will YOU do? Should I give him a break? I don't want him to freak out and then he leaves me!
