What do you think about this?

There's a guy i'm dating for sometime. In the beggining it was all very good, he really seemed into me, i know his friends, they seem to really like me, he met my sister and my mother. Lately we had a long weekend and he just disapeared. He was gone for five/six days. Before he told me he was going away for a while and when he'll come back, he would call me. I wrote him once a message if he was back and i miss him, i saw it got delivered, but he didn't write me back. Then after few days he reappeared, we met up, his hand was broken, he got into a fight, he was away with his friend. I said i wasn't exactly happy with his bahaviour and that he should take care after himself and stop doing foolish things. So we spent an evening with his friends and he took me home. Next day i asked are we meeting up, he said he was thinking about going out of the town, but he would call me to know what is exactly his plans. Never got that call. Wrote him, what are you doing, didn't forget to call, no reply again. Don't know what to think....
