Am I overreacting about NSFW content?

Hi, this is my first time posting, so I’m not sure if this is the right place, but I need advice because I’m really struggling.

I (21F) have been with my husband (21M) for 3 ½ years. We just got married this month, and I’m currently 3 months pregnant with his child. While I love him deeply, there’s been an ongoing issue in our relationship that I can’t seem to resolve, and it’s weighing heavily on me. Throughout our relationship, I’ve caught him looking at NSFW content multiple times. This includes following OnlyFans creators, looking up specific girls online, and even texting other women. Every time I’ve found out, I’ve told him how much it hurts me and makes me feel insecure. I try to explain that it’s not just about the content but how it makes me feel disrespected and not enough for him. He always brushes it off with comments like, “It’s just porn,” or “I don’t want to bother you with me being too sexual.” When I try to have a serious conversation about how much it hurts, he seems annoyed or aggravated, like he doesn’t take it seriously. That just makes the pain worse. There have been times I’ve spent days in bed crying after finding something. I’ve felt so broken, so insecure, and I question my worth constantly. But no matter how much I cry or express my feelings, nothing seems to change. He just goes back to doing the same thing. It’s gotten to the point where I feel like I have no choice but to let it go. If I see something, I don’t confront him anymore,I just cry when he’s not around. To make things more complicated, outside of this issue, he’s perfect to me. He’s caring, hardworking, and supportive in many other ways. I honestly couldn’t ask for anyone better in every other aspect of our relationship.

Some of my friends and family think I should leave, saying it’s disrespectful and that he’ll never change. Others tell me to overlook it because of all the other good things he does and because “all men do it.” I’ve tried to think about it from his perspective and convince myself that maybe I’m overreacting. Maybe it is just something men do, and I need to work on my insecurities. But at the same time, it’s a constant thought in my head, and I can’t seem to let it go.

I love him so much, and he says he loves me too. But I feel stuck. I don’t know if I’m being unreasonable or if I’m allowing myself to be disrespected. Should I stay and try harder to accept this, or should I draw a line and demand change for my own mental health?

I would really appreciate any advice or perspectives. I just feel so lost and don’t know what to do.

Edit: He still follows mainly nothing but nsfw creators on social media and all of his community on here are sexual. As of the past year/2years he hasn’t texted any other females and stopped paying for OF in ‘23.
