It happens so just give him some space to think things thru and calm down but don't force the situation as youll just make it worse. Its times like this that tell you what your relationship is really at so be patient and he will be back soon. Good luck
okayyy hey there . Well firstly you gotta find out why hes angry , if hes mad at you because he thinks you are lying to him or something , tell the truth and be honest with him , guys sometimes think you are doing something which you are definitely not doing so assuring him you aren't doing any of these things will make his life better , also if hes mad at you because you were late or forgot something apologise say you will make up for it type thing . I guess this situation really depends on what hes mad at , usually if hes just ignoring you , give him some space don't fully try to ask him a trillion questions , let him calm down and talk to him about it .
