Husband liking naked Instagram photos

So my husband will not like any of my Instagram photos (mainly our kids) and I only post once every 1-2 months, I prefer Facebook which he is not on. He does like nearly naked female photos daily. Now we are both 45. All of my kids are with him but I have worked very hard to maintain my weight and figure. Our sex life is not lacking. I never say no. My confidence has taken a HUGE hit because I can do Botox, workout daily & do my makeup and hair but let’s face it, I won’t be 23 ever again. I am seriously considering ending my marriage over his “liking” of naked photos. And I’m a liberal wife. I don’t care about strip clubs or porn but publicly “liking” nearly naked photos is SO embarrassing to me. I don’t even want to be intimate anymore because I am nothing like these other women. Be brutally honest. I’ve been divorced before and I’m like “F it, I survived once and I’ll survive again.”
