I'm sorry that you can stay a couple of more days in Ireland, but you can always return at a later time and enjoy the country.
As for what to do when you return home, you already have a good idea to stay light, be pleasant and keep the focus on you and what you need to do such as unpacking, reviewing your mail, and getting back to doing the normal stuff. As for the wedding coming up, that's your decision as to whether or not to go...but things do change and so will your h's anger...give it a couple of days and see how things go before making your final decision.
Travel safely.
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.
