I'm sorry to hear about this for you, CuteJill. I was married and subsequently divorced due, in large part to that fact. My ex liked tickling, thought it was fun, but she didn't love it and actually hated the idea that I had a fetish for it, but never revealed that to me until after we were married, when she gave me the ultimatum of get psychological help or we are through. As you can tell, we are through.
I did learn, over the years, though, that you must hold out for the right one. It may seem frivolous to you that love of tickling is a reason to hold out for someone, but if you love it, it's not frivolous.
Good luck. You will find someone who loves it as much as you.
