My husband couldn't tell me I'm beautiful

My husband and I have been struggling in our marriage. There has been infidelity on both sides. We have a 3 month old baby and are trying to make it work and save our marriage.... We've had our 5th kid and I feel so gross and ugly. Me and my husband don't talk as much as we used to and I came up to him and asked does he still find me beautiful. He groaned at me and said "What kind of question is that?" I said I was asking and he said "Idk. Do you think Marilyn Monroe was beautiful?" I said yes and he said "And now she's nothing but bones. Probably dust. Angels are seen as beautiful but the biblical angels are actually quite terrifying is you truly real what they're supposed to look like." I asked what his point is and he said "My point is it doesn't matter. We all end up rotting in a box in a ground and even things society says are beautiful if you really look at their description they're not. In the end nothing matters. Obviously I wouldn't have married you if I didn't have some kind of attraction to you now stop asking." I get we are in such a rough spot in our lives right now but he couldn't at least say "Yes you're beautiful?
