Forgive me if this is too touchy feely personal:
I too am recently divorced. Since it was my X who introduced me to WDW...and actually proposed to me at the Poly luau, my married life memories are VERY tied up with the MOuse. We went every year....engagement ,honeymoon, pregnancy, baby-toddler-teen daughter.
Unfortunately, X also took the other woman to Disney!!!!
BUt I refuse to let his betrayals and just plain rude behavior sully my love for the mouse. THat being said: be careful!. Your frame of mind when going to Disney solo can alter the experience. I found myself getting misty watching Wishes this December...even tho I was there with friends...if I had been alone, I think I might have lost it completely.
When I go now with my daughter, I can still remember all the good memories with her as the focus (meaning I don't dwell on the memories of X).
NOW A FUNNY STORY:
Have two bricks at Disney. A family brick in front of MK and another over by luau cove announcing our 'engagement'......Next time I go to Disney I think you might find me chipping out X's name in those bricks!!!!!
Hope I don't get arrested
Finally: my daughter remember EVERY time she went to Disney because when she was a baby, we videotaped HER...and since she's watched those tapes so often....she has a 'memory' of all her toddler years. I think a 6 year old, even without videotape, will long remember his vacas with dad....especially during what must be a very difficult time for him with the divorce.
So dad....go solo and have a grand time. You will see things and think: oh I wish son was here but you will also see Disney from another angle and that is always a good broadening experience.
