HELP I don't know how to feel

Ok so back story, my SO has two kids that I consider mine and so does he since their mother left a long time ago. We don't live together but me and my SO live in Florida and as you guys know Irma just came through here and hit us pretty directly. He took the girls and went to Disney to stay in a hotel there and I stayed with my family. Everything was going ok until about 9:30 last night the power went out and I couldn't get ahold of him to check on him and the girls and this went on for about an hour about 10 texts later and 2 phone calls he tells me he is "fuckin sleeping" so I leave him be, today I haven't heard from him besides him reading my texts even tho I apologized and told him I was worried. Should I be mad at him or does he have a right to be mad at me? I just wanted to make sure my girls were ok and not scared, what do I do to make it better? This has now been 12 hours...
