Hi. I am so sorry for your loss. Your trip sounds amazing.
I too am a huge believer is the spirits. My husband passed about a month ago. The Saturday afternoon the memorial service I had this overwhelming desire that I had to go to the beach. I was having this inner war about going to the beach or taking a nap. My normal spots were unavailable and I ended up guided, no doubt by Kevin, to the area of the beach where we had gotten married 9 years before (he died the day after our 9th anniversary). I got to the beach and there were waves and a surf contest. One of his favorites things. I watched for awhile had a cry and found this peace I needed and it's been that way ever since. I miss him a lot but he took me back there to bring it full circle. At that moment I also realized that the accident happened (motorcycle accident) where we meet 14 years ago for our first date.
When he was here he was jealous of my ability to feel so deeply and see things. Now I think he is using it to his advantage and grateful that I recognize the signs and follow the breadcrumbs when need be.
I am glad you enjoyed your trip and knew that Mark was there with you the whole time.
