Relationship in crisis

Me and my partner have been together nearly 4 years , we have our ups and downs like any normal relationship. We had a big argument on the Saturday afternoon and was not talking to each other and then the evening came and he stormed out of mine without saying a word , I have tried to reach out to him as I feel like I’m to blame for the argument, since he left mine , I’ve had no contact what so ever from him even tho I’ve tried to ring him , text him, even messaged on social media but his ignoring it all .

I don’t know what to do?

Has anyone dealt with this before if so what was the outcome ?
