is my boyfriend acting sketchy or am I paranoid

Past couple of months I've noticed he won't charge his phone at night. He uses his phone a lot so I know it needs charged. He sleeps with it under his pillow on the side opposite of where I sleep. I haven't tried going through his phone or anything in awhile. But last time I asked to, he wouldn't hand me his phone. He was the one holding onto it & just scrolls through everything, like he's trying to hide something. Idk. Sometimes when I am next to him he will kind of turn his phone away or not open messages, even if they're just from his friends. I mention it and he's like "why does it matter?" Last night he actually charged his phone while we slept. I woke up to just use the restroom. Didn't even touch his phone...  came back & he woke up & put his phone under his pillow. I asked him why he didn't just keep it on the charger & once again, he said "why does it matter? Would you like me to plug it back in?" Of course I said no, because then I just look crazy & I feel like taking reverse psychology. He knows I'd feel crazy saying yes. 

Today he was backing his phone up on my computer because his computer doesn't have iTunes. His pictures obviously were uploaded onto my computer & he took the time to delete all of them. I asked him why he'd take the time to do that. You see, I only got two hours of sleep last night studying for finals. I got up at 9 am to study then take my exam, then worked from 4pm-12am & it was already 1230am at this time. I had to stay later becos my coworker was late to work. and I needed to leave so I could sleep. It's 30 mins past my shift. I told him I'd just delete them when I get home & he said no, he will just delete them now, it'll only take a couple mins. I said he's acting sketchy lately & he talked to me like I was crazy. 

Not only that, but he used to be super loving. Whenever we'd fight he'd force me to stay at his house or in his car or mine until we get everything out even if it took an hour. I HATED it, but the way he screamed at me showed he cared. He would feel bad if I cried & would stop arguing to comfort me. If we were texting, he'd fight with me but wasn't always really rude. We got into a stupid fight a couple days ago. We don't fight often AT ALL, but whenever I try bringing up anything that is bothering me he just says "I'm not reading that", he used to read everything I sent. Now he always just assumes I'm trying to argue. He says to talk in person, so I try & he acts annoyed. & tells me to be "short and sweet", as in don't talk for a long time. On Monday we argued & I started crying and he wouldn't listen to me. Instead he acts HEARTLESS like he doesn't give a shit about me. I was BAWLING my eyes out & he just grabbed his stuff to leave. I was telling him I don't feel loved anymore because he's always just talking about fucking me or grabbing my ass. He doesn't just kiss me, & when I try or ask he sighs or I have to ask multiple times. He just acts a lot different than he used to. And the whole phone situation has me thinking something's going on
