Greetings Tracie,
Have you considered trying to contact him yourself? In the year I've been on this site alot of people have surprised themselves by being able to contact their loved ones in the Afterlife. Your connection to him can be very valid and certainly sounds strong enough to get you through to him.
You'll need some quiet time, maybe a few questions prepared ahead of time, and
you already have the curiosity and intent. At first you may think it's 'just' your imagination, but as you get more into it, you'll be amazed at what you find out!
Feel the love in your heart you have for him and mentally state that you wish to contact him now. Pause and wait for a sense of an answer--almost hearing a hello, or feeling a change in the energy around you. Then ask a question and accept that you may sense or hear an answer, then go with it!
If you have time to get a Moen book called Afterlife Knowledge Guidebook, you'll do alot better, but this can get you started.
Best wishes with it and let us know how it goes. You may find that you like being in communication with the other side and can use the abilities that SI's situation gave you to help others later!
Bets
