Heavily pregnant and fiancé keeps looking at corn
So me and my fiancé are close in age. We are both 29 within the same year, and maybe he is still immature, but also he is going to be a father, and I am 36 weeks pregnant with his child, and this has been a problem in the past with him looking at porn and women online consistently, and he said he wouldn't do it anymore because I brought up that I didnt feel comfortable with it and it makes me feel ugly, and like he doesn't love me, despite him saying he does. He is always super suspicious of me and always accusing me of the baby not being his, even though I have never once given him any reason to believe this way, and one time he was convinced I was talking to my ex because he saw a group chat where someone had, not the same, but a similar name, and he called me a foolish woman that would destroy her home, and all this other crap, and he said I was talking to my ex, which makes no sense since I am literally carrying his baby and living with him. Makes sense that he was paranoid and jealous now that he is always suspicious of me, because it's him, and I feel like he feels guilty and projects it onto me, because today I found more porn and half naked women he follows online on his social media accounts. I had another talk with him and told him I don't want him looking at that stuff because that's how cheating starts. It starts off by just looking at stuff like that online, and it may seem innocent, but not eith lying and secrets, and not until it becomes a real woman one day... But literally not even 30 minutes after I asked him to stop doing it he was doing it again right there, and when I confronted him and asked him why he is doing it, he wouldn't tell me why, and he just kept saying I was crazy, and asked if I feel like I have dementia and stuff, and he outright refused to tell me anything about why he does it when I asked him, because he wouldn't at all admit to it that he did it or does it at all, even when I told him I know for sure that he was, and kept asking him why he does it, but he wouldn't tell me. He got all mad, defensive and weird, and said "No, I don't look at other women because you said you don't like me looking at other women, and so I respect you, and I don't look at them like that." But I literally saw it, and I told him that it hurts me that he was doing it again... I told him I am not stupid, and I am not crazy. I literally saw it on his phone, and I got his phone this morning and took pictures of his google history of an porn video of a woman he looks at on tik tok. I literally have proof. I never deny him when he wants sex or anything. I always cook and clean, and I am never mean or talk badly to him, and I only ever show him love and respect. I don't know why he keeps doing this... he says he respects me and our relationship, but he clearly doesn't, and I don't feel like he really loves me either, or he at least wouldn't lie about and hide it or try to say I am crazy, at the least... the worst part is the lying and hiding it, and gaslighting me for pointing it out or being upset over it... It's not even the fact of what he is looking at, it is the fact he won't admit to it and it's a secret that makes it feel like he will cheat on me eventually physically. I feel that if it's not cheating in his mind, then he wouldn't feel the need to lie about and hide it from me, and would be able to at least tell me why he does it. But be honest, am I really just overreacting? But my problem is that he isn't being honest, he is hiding it, and worse yet, he is trying to lie and gaslight me saying I am crazy. I don't know what to do. We live together, and he keeps saying he wants to marry me, but within the same day he tried to marry me, he was looking at porn and naked women... not even an hour later... we didn't get married that day, but I don't get how he can one minute say he wants to marry me, and the next be looking at other women again when I asked him not to and he promised not to. We are about to have a baby together within the next few weeks or so... What do I do?
**TL;DR;** : He keeps looking at corn and denying it even though I have told him several times I don't like it, and I dont know what to do.
