Am I overreacting ?

i’ve been married with my husband for a year now , and i’m 37 weeks pregnant, two days ago I caught him liking a video of a girls butt on a girls sexy page I guess you can say. None of those girls look like me I’m a petite women ( before I got pregnant of course ) about to months ago I checked his phone and I also found history of watching insist port , aunt / mom type . This is not the first time a little after we moved in together I also caught him watching porn for days. I randomly checked his phone , I actually thought he was so in love with me now call me what you want but ever since I’ve been with him I’ve never even thought of looking at other men . I thought it was the same with him . He even had screen shots of pictures of porno girls . I was so devestated it took a while for me to get over it and he promised to stop and he swore he understood my point of view . It’s just not okay with me . At all specially considering at that time I was working for both of us he wasn’t working I felt humiliated . Forward to this last time I saw his history I didn’t say anything . I just felt disgusted , and depressed and I know he noticed because he was being extra nice. At this point I don’t know how to feel ? I’m confused and I feel fat , un able I know this is temporarily and I can get back to my shape but my respect for him I don’t know I need help and advice please . I don’t really have anyone to talk to my pregnancy hasn’t been easy as it is . I’ve felt so alone and he’s all I’ve had but I feel so disrespected . I just would never . I can’t even see him to his face or lay next to him because I’m just so angry
