My husbands a porn addict?

I just found out my husband was watching porn every day the past few months, yes we still have sex every day or other day but its always quick and easy. Now that I think about it, he acts out like what youd see in a porno. It hurts cause hes watching this when Im not around but never asking me for pics or actually, never really compliments my looks at all. These women look amazing,and it just makes me feel insecure. I dont want to divorce him but I dont want to feel like I have to compete with these women. I asked him to stop, he says he cant. Help?
