Breathe! You don't want to have a go at him when you are angry, hurt or disappointed. The best thing to do is settle down a bit and wait 24-48 hours before you say or do anything. You need to prepare yourself for how he will react if you were to tell him about the ow.
Don't worry about the language, i.e., we understand that there are times when it slips out.
Breathe! Find a pillow and beat the stuffing's out of it. Take that anger and put it to good use on a project that you've put off doing.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
