Porn in a relationship

I need to know if I'm going crazy. My husband when we were dating was very loving and had high sex drive. He has a stressful job and I understand it's exhausting and we have things that keep us busy but i just want him to love my body physically the way he looks at and wants those women. We have been together for over a year and in that time he slowly stop wanting me sexually. Now I've caught him with so much porn in his phone of other women's asses and him looking women up by name to see them. I've confronted him about all the porn saying I didn't like it but he continued. I'm at my breaking point please what should I do. I feel like he doesn't want my body anymore and I haven't gotten fat just a little pregnancy fat which isn't much. Should I tell him to get counseling together or should I leave. Please help
