Boyfriend watches porn.....

My bf and i have been together for 7 years and counting, we have a daugher together and im currently 31 weeks with our second. Lately for the past few months our relationship seems like a blurr, no spontaneous sex anymore hardly communication, and recently ive come to find he is watching porn again. Being a chunky monkey that i am makes me feel so much more insecure. He tells me if i want it i can show him and put effort too but anymore i feel whays the point if he just chooses to use porn for his needs then clearly he doesnt feel the way i thoight about me sexually anymore...... I just dont know how to feel or what to say/think anymore 😢
