I haven't heard from my boyfriend in 2 weeks. Sometimes people need time & space to themself but how long is too long? Is it over, what should I do?

I have been dating my boyfriend for 5 months now. We are in a long distance relationship, we're a 3 hour drive away from each other so it isn't too bad. Before we started dating I asked him if the distance would be an issue, he said it was not. Things were great, we talked almost everyday on the phone, videochat, we saw each other in person & went on dates. He told me that he wanted to be with me & that he found what he was looking for, he didn't need to look any further. He made it official with me after one month of dating. We have been in a committed relationship now for 5 months. Recently he has faced hardships back to back. He had his own moving business but things fell apart when he experienced a car accident due to the negligent driving of an employee. The employee crashed a moving truck damaging the customers furniture inside. The customer may try to sue him because of this. Shortly after this incident my boyfriend got in a car accident on his way home. His car was totaled. After that he seemed to get depressed. I noticed that he started calling less & answering the phone less. We were supposed to see each other Jan 29th-31st. He didn't call or come. He called 2 days later wanting to see me but I was upset with him so I didn't answer my phone for 1 day. The last time I spoke to him on videochat was on February 3rd. I told him that I was upset that he did not spend time with me like he said he would. He apologized & said he has been going through a lot. Feb 3rd we discussed me coming to his area to spend time together. I was going to travel to him. He said he wanted me to come, he agreed to it & we would talk about it more. He was happy to see me on videochat, smiling, everything seemed fine. Feb 3rd was the last day I spoke to him. He hasn't said anything since then, no calls or texts. I called him numerous times & left messages. I spoke to his brother he said he talked to him a few days ago. Should I wait & see if he reaches out or should I move on?
