Porn thoughts..

I've been married for about 8 months now, but have been with my husband for 5 years. About 3 years ago I started having stomach issues and that also brought relationship issues. Because of my stomach issues we barely had sex..(but he was still horny) leading to the relationship problems. I found porn sights on my husband's phone and explained to him how it made me feel. My mom passed away about a week ago so I haven't really been up for sex, but he keeps trying and pushing. This morning I went to the bathroom to find him looking at porn and it just broke my heart. It makes me feel like I'm not enough and honestly I don't think it's any better than cheating. Your thoughts?
