Help..

Selina
I been with my now husband for 6 years and we just got married a year and half ago. He is a good man I could say and for a fact he has never cheated on me. I found out he's been watching porn these past 2 days and not only that he watches those half naked girls making sexual videos. That has hurted me alot all day today and I am determining whether to leave him or not. I don't know if it's considered cheating but it sure ain't loyalty either. It makes me feel like shit and I just don't know what to do. . Help?
