Is porn a form of cheating?

Is porn a form of cheating? I don't think so until it gets to a certain extent.

TMI but my fiance and i use to have sex at least 2-3 times a week. Until august then it's been like once a month. I have to ask him to have sex with me. And it's starting to tick me off.. I'll ask to see his phone every once in a while and low and behold he has fuckin porn in his prrvios searches.. I feel like when you watch porn more than you have sex with your fiance, then its a problem. He just thinks I'm crazy. I'm currently 16 weeks pregnant. & he makes me feel completely unattractive. 1.5 years later. How the hell do i keep doing this? & no, it isnt all about sex. But fuck meeee, it gets on my nerves. He's not an affectionate person. And he doesn't comminicate to save his life. I've literally given up. How can anyone do this? Anyone have advice?

It could mean so many things. And he knows how.much his lack of affection and giving a fuck means to me, but it doesn't change.

He just says I'm crazy. Like...how? 🔫 🔫 🔫

P.S.

I don't have anything againat porn. I watch it myself, but rarely. I believe everyone needs their own pleasure once in a while.
