My (21F) boyfriend (26M) were together for 6 months. I had asked him to think of something fun for us to do this weekend and it was basically meant to be a surprise. He wouldn't tell me what he had planned; just that he would be coming over Saturday.

On Friday afternoon, he texted me that he was going to go bowling with his best friend and would text me when he got home. He mentioned that he may go drinking with said best friend, but wasn't sure yet. He didn't text me at all that night, which wasn't too unusual because he's forgetten to do so before. The problem is, I didn't hear from him all the next day either, which was the day he was supposed to come over and "surprise me". He never showed up and I started to get extremely worried about him. I know a day isn't a long time in the grand scheme of things, but this is very unusual behavior for him. I text and called him multiple times to see if he was okay, but neither of them would go through. I'm pretty sure that he blocked me.

By the time Sunday morning came around, I was full-on panicking and felt physically ill. I had a mental breakdown while talking to my mom, expressing my worries that something bad had happened to him. I didn't have any of his family or friend's phone numbers and didn't know how I could find out if he was safe and sound. My mom did an online search on his dad and found his phone number. I guess this is where the situation gets hairy.

His dad was very kind and understanding regarding my concern. He revealed that my boyfriend frequently drank too much and would sleep for days afterwards. He expressed that while he was concerned about this behavior, it was completely normal for him. However, he did see him driving back from a town a few hours away on Saturday while he was out there himself.

His dad subsequently gave the best friend my boyfriend went bowling with my phone number, and he reached out to me. He told me something similar; that my boyfriend had a habit of going overboard with alcohol and "needs to get his head out of his ass". That's not what bothered me the most, though. The best friend revealed that he had no idea that my boyfriend was even dating someone, despite my boyfriend telling me all his friends and family knew about me. He also said that my boyfriend hadn't gone drinking with him, like he told me he might, but had left Friday night to go drink with "a friend".

My boyfriend has told me before that he doesn't drink anymore, and the fact that he was out doing so with an unknown friend while he was supposed to be at my house is extremely concerning. However, I decided not to press the issue yet. I wanted to give my boyfriend the opportunity to text me back first and tell me what was going on.

He text me back just an hour or so ago to tell me that I had crossed a line by contacting his dad and that we were done. I begged him to let us reasonably talk about everything that had happened before making such a drastic decision and he proceeded to block me everywhere.

AITAH for contacting his dad? I never meant to hurt him or cross a boundary. I just wanted to know he was safe after he didn't show up and didn't text back when he said he would. I didn't know what else to do.
