I desperately need help and I’m going to try to keep this brief.

Today my husband and I were on the couch and he was showing me something on Snapchat and I noticed he subscribes to two porn stars. He quickly shut the app, obviously trying to hide it from me. On the surface this probably doesn’t seem like the biggest deal but here’s a little back story. First of all I’m 27 weeks pregnant, not super relevant but is just making this all harder for me. I’ve always known he watches porn but it’s never really bothered me. I guess because it’s just so mainstream and also because we’ve always had such a great sex life. Recently our sex life has gone down hill. I genuinely don’t think it’s because I’m pregnant because he always says how me being pregnant turns him on even more. When I brought it up to him about a month ago, we talked about it and he disclosed to me that he masturbates daily (with porn). We continued talking and he admitted that he felt that by watching so much porn his view of beauty got altered making him less interested in sex with me. I am a very sexual person and fully believe that masturbation is healthy and normal. But everyday and always to porn, to the point that it’s affecting our sex life does not seem normal to me. Since this talk about a month ago we’ve talked about it a lot. It usually ends up in fighting which I hate because I want us to be happy and strong before the baby comes. He has said that he will stop (I don’t really believe him) and our sex life has been a little better. Until I saw this snap chat thing today. I can’t help but feel like this is a new level - I feel like this could lead to something even more unfaithful. I am scared, hurt, and just want to enjoy the happiness my baby girl is bringing to me. I’m asking for advice from people who’ve had similar experiences or just think they might have some good advice to share. I am already so distraught and sad so please don’t say anything hurtful or tell me to just leave him because other than this issue he’s a great man and I do not want to leave him. Thank you in advance.
