Hugs, Mommy! mahirap po yung pinagdadaanan niyo because it affects not only your relationship but also your self-confidence. Pero please remember that this is not about you and how you look. You are beautiful kaya siya na in love sayo in the first place.
The issue now is pornography inside the marriage kaya siguro hindi ok ang sex ninyo lately. Yes, it is common for men to have the tendency to watch porn, pero kahit common yan, it doesn't mean na OK yan. Pornography within marriage is an unhealthy habit and damaging ito sa intimacy ninyong dalawa na dapat sainyo lang.
What you can do, Mommy, is to talk to him in a very loving way na you want your marriage to be stronger and to point out that seeing those photos is hurting your confidence. Then maybe you can invite him for a getaway. Magbakasyon kayo or kahit mag-date man lang. Intentionally put yourselves in a romantic environment. honestly kasi nakakadrain sa bahay pag lagi na lang kayo nandoon. I wish you all the best, Mommy! Basta don't ever forget na you are beautiful, please!
