I want to cheat

I am a married mother of two beautiful babies, a housewife and an artist. My husband is heavily addicted to his phone and pornography. He has stopped showing me any affection or intimacy. I’ve asked countless times to work on our marriage but he never puts in the effort. I’ve always been curious about dating women and I’m often fantasizing cheating emotionally and sexually. I never expected myself at this point so early in my life. I’m only 27 :(
