cheating? I'm in desperate need of advice!

Shyann

so I don't like talking about my personal life but I'm just so confused and don't wanna talk about this with anyone I actually know, at least not right now. y'all be kind now please. yesterday my husband was mowing and I was cleaning the kitchen and his phone was on the counter, I never ever look at his phone because I trust him, well did, anywho he got an email and normally I just ignore when he gets a text or something but my gut was like look at his emails, so I did and nothing crazy until I get to his spam folder. well I see these weird emails saying like "hey, is this insert husband's name" and weird short crap just like that and most from the same email. also a message in there said it was from Emma Watson and she wrote stuff like leave me alone you weirdo it was a one time thing and stuff like that. the emails seem to not actually be from a real person but like a website or something. so I then went to his internet history and didn't find anything until I got to his downloads and in his downloads I saw some sex stuff from websites and then I saw a picture of some woman's vagina and I think it said from sextnow or something like that. so then I went to his app store and went to his apps that he had previously had but uninstalled them. then I saw a crap ton of different webcam app things and then I saw tinder. what the hell? I tell him all the time I'm always up for sex. he works alot and is exhausted once he gets home from his routes.so I dont even try to initiate it. I can't read him very well and got tired of being turned down. we have a 3 year old and I am currently 9 weeks pregnant which was one of his mother's day gifts to me, to try to have another baby. i also recently had a miscarriage. I'm confused on why he wants another baby if he isn't happy with me? I'm a stay at home mom and don't have anything. I can't just get up and leave. with no money or anything. i also am only 22 years old and refuse to be un happy and live the rest of my life misserable. obviously he isn't happy? what do I do!? I haven't confronted him yet because I don't know how and I was kinda wanting to see if I can figure out anymore to the story on my own by snooping. advice would be so appreciated!
