Shady boyfriend dissapeared update..

I start nursing school in 2 days.

I am super excited! I have all of my education saved up for and everything packed for Monday.

He asked me to be his girlfriend in May.

Everything was going great, until about 3 weeks ago, where my boyfriend was acting very distant. He got in a car accident and failed to respond and answer my calls like he had been doing.

He was badly injured, his car was totaled, and he told me he was depressed, something he never experienced before.

I was there for him. I was working 100+ biweekly, so we talked when we could.

He even planned for us to go to the baseball game and the zoo in September. And that he is moving soon, but will be just as close to my apartment suite.

It was all pretty shady with not responding to me as much, but I chalked it up to the side effects of the pain medication.

I just talked to him 2 nights ago and how I was going to come over, but he was taking care of getting a rental care for the weekend, insurance, and his work.

Then yesterday morning I noticed he didn't respond to me and that he even unfriended me on Facebook. . . These actions are just not like him.

We were together for only 3 months, but he was so sweet. I only wonder that he was too good to be true. That if he was someone totally different in the inside. Long story short, we don't talk anymore. Just like that he is gone. He has disappeared. I don't know what happened. I don't know why he chose to act this way. I am 19 and he is 27, so it could've been age, as he wanted children soon and I told him it would be a good 8 to 10 years for me. Believe me, I want to call him 5 times, but I know he won't pick up.

Has anyone else ever been ghosted?

This feels so odd.

Anyways, I guess there are brighter days to look ahead at.

I honestly have no idea what happened. He could have killed himself, he could have not had enough money to pay rent and need to go back home in Cali, he could just be a weird person.

This is what scares me. Three weeks ago he got in a car accident and before he told me this I had a guy feeling he was in a car accident. Now he has vanished. I haveba guy feeling this car accident and life was too much for him and he committed suicide.

What do I do...?

I don't want to be that annoying "ex". I don't know what's happening at all with him although I told him it's over.

What would you do?

UPDATE:

Thank you for your advice, it's really helped so far. I know a lot has happened to him in such a short span. I feel like calling the local police to conduct a welfare check. I looked it up. It's when a loved one does not respond for a while. Just to check if they are okay. So I would tell the police briefly that he was my boyfriend but we are not together anymore, that he talked about dates and plans for September 3 days ago, and he stopped responding 2 days ago and I can no longer contact him. That I don't need answers from him, just that I want to know if he is alright since he mentioned to me he was feeling depressed after his car accident.

I totally lost the paper with his address on it. Could I just tell them the Avenue his complex is by?

Would this be a bad idea..? Or should I just not see if he's okay? I mean he probably is but then again he just could not be. No updates on his social media.
