Husband watching porn

I have just looked at my husband's tablet to discover hundreds of porn (not bad go to jail stuff ) but normal everyday stuff the problem is he would rather stay in the sitting room that than come to bed with me. I am over weight and don't like my body anyway but it's making me feel like I'm not good enough anymore and he needs to watch this to have sex (hardly ever )with me. Does he imagine it's one of them instead 😢😢😢xx
