i’m going through withdrawal because my boyfriend is ignoring me

yesterday I went out with a (male) friend at around 1pm. my boyfriend hasnt met him, but my friend has a girlfriend and there’s proof, as well as the fact that he’s expressive about his love for his girlfriend. anyway, that entire morning my boyfriend seemed a bit off, but he said he was just sleepy since he was working, so I brushed it off. I came home around 4pm alone, texted my boyfriend, and got no reply. I assumed he was taking a nap, so I wished him a good sleep, and told him I loved him. I got no text for 12 hours (since 1) and in that time I sent some texts such as “hey baby, I hope you’re okay! love you❤️” and “text me if you can!”. that might sound obsessive, but him and I are inseperable and text 24/7 when we aren’t physically together. anyway, I woke up and immediately saw he didn’t text me, but was at work. I was already having mental jumble the night before because of an argument with someone, but when he didn’t text me I literally started shaking, sweating, and my stomach formed a pit. I asked him why he hated me, and he said he “didn’t want to talk” and left it at that. i’m losing my mind, he NEVER does this, and we’re so clingy. i’m literally so sad, and i’m not sure if it’s connected from me hanging out with my male friend or not, but I keep asking why he’s ignoring me and he just ignores me more.
