Idk why this shit offends me

I’ve been married for almost 3 years and it recently occurred to me that my husband loves masturbating. I caught him several times paying for videos from random women on social media. After the last time I told him that if he can’t stop paying for videos (we have a baby on the way) then I’m leaving. I don’t feel like he ever craves me the way he does other women. He’s willing to spend $50 for a 10 second video (meaning he spent hundreds of dollars on this shit). The other day I came back home and caught him masturbating to pictures of me when I was younger. Like mf I JUST LEFT! WE COULD HAVE HAD SEX! His excuse is that I’m not confident in myself anymore. I’m like take a wild fucking guess at why. Outside of pregnancy I’m sexy af, and I think he forgot who tf he’s married too but this masturbating shit is for the birds. Where am I supposed to get attention and dick from?
