I (F20) pressed my boyfriend (M21) on a question and now I regret it

My boyfriend has been staying with me for about a month now. When he’s been here, we don’t do anything except watch tv or sleep. I asked him today if he’s doing ok and just got a weird look. I then asked if everything is ok between us and he just said “there’s nothing to worry about”...<br><br>That night, I was doing some laundry and noticed some semen stains in tissues on the garbage. I was pretty sure it was his and that he’s been sexting some girl. I confronted him and he confirmed he’s been sexting her for a few weeks but it means nothing. He said they never met or hooked up and he never sent any nudes. I’m really upset about this but idk if it’s such a big deal since it was only texting.<br><br>Here’s the weird part. He asked me to show him the messages she sent him that he responded to. I gave him my phone and he was reading the messages and got really upset. He asked me what some code word was and I didn’t know what he was talking about. He got really mad at me and left my apartment.<br><br>He hasn’t come home in two days and won’t answer my calls. I have no idea what to do.<br><br>**TLDR**: found out my bf was texting a girl, he’s angry I didn’t give her phone to him, he won’t answer my calls and won’t come home.
