Help.....

So me and my BF  where angry at each other but he won't bring up the conversation about why we mad so we can talk about it and neither do I bring it up 
So he wouldn't even let me kiss him or anything a few days ago we were cuddling & aswell we had sex but should I assume everything is good or should I just bring up because the way he texts me is not the same so should I just bring up the conversation
