Am I being rude to my bf?

.

Ok so we all know us girls get paranoid af if we sense something is off with our man, this is my story. Ok so my name in my bf’s phone is just my first name. I’m not sure if I had a dream that I saw a message pop up on his phone with just a girl’s name (it was long and started with a D) but anyway, I took aware of it either brushed it off. When we woke up one morning, his phone dinged there was a text from his mom which I obvi don’t care whatever. But yesterday he got a Snapchat notification noise and he still hasn’t opened it yet. But I looked at his phone once and the notification (of another time this happened) was gone. I joke around that he’s got other bitches and he thinks it’s funny but he says he doesn’t. He made a point saying he doesn’t have time and he’s not like that. He works a lot on campus and is busy with labs and class. We spend every weekend and night together. Sometimes he takes his phone to the bathroom when he says he has to poop that makes me wonder why he takes a half hour to poop. Like does he mean he actually goes and jerks off on the toilet?? (effing gross and weird) He’s not a big social media user but he uses snapchat. He’s annoying in that we’ll have sex before bed but when it’s late like 1am and he wants round two i say “no” but he’s just like “please just a few strokes” and I then I yell at him “no!!! it’s late and I need to go to bed bc I have I wake up early!” He also got up to piss in a bottle and go back to bed like wtf 🙄 he pisses me off like he wastes time by making stupid jokes or distracting me and so I ignore him and he’s like: “your ignoring me :(“ a lot of the times he’s like a couple or few mins late to class because we’re arguing I’m not having sex with him bc it’s a waste of time and he’ll be late but he’s like: “pleaseeee I’m so horny” like omg?!?!? So he tells me to “quit my bitching” but I tell him, “I bitch because i know I’m right. You wast time and your gonna be late” he’s like “that’s gotta stop” HE DOESN’T LISTEN!!!! So my paranoia is that he is looking for another girls (still don’t know if the thing about the text with the girls name is a dream or not) because I complain about him slapping my butt while I’m tryna get ready for class fast because he wastes time bc he had to have sex. We used to do anal a year ago but tbh I never wanted to in the first place and now he wants to start again and I said no!!! And he’s like “please let me just put the head in.” Sometimes I think my period week is great bc no sex or at least not as much. We’ve been together for almost 2 yrs and like in a long term relationship, there comes a point where you don’t have as much sex. Pisses me off!!! What do you think. I can be a bitch and say mean things bc he doesn’t listen no matter how I approach it. I’m a being rude? Do you think he is trying to talk to other girls bc i bitch too much? This is what I’m mad about today 👿
