Great question!
My hubby, better known around PLEBA as Big Rick is the THE most tolerant husband in the world when it comes to my obession! He's not quite as into them as I am but he tries SO hard to know things about them so he can impress me with his U2 knowledge. He always puts a U2 CD on in car for me, takes pictures of U2 related street signs and buys U2 collectables on ebay for me. He indulges my passion for vinyl by taking me to used record shops on the weekends and made sure I had tickets to every Elevation show I wanted to go to. He's 15 years older than me so I give him so much credit for doing all this for me, just because it makes me happy.
Every now and then, I detect a little annoyance or maybe jealousy if I've gone on too long about Bono but other than that, he's great about it. He'll watch videos with me and ask questions and he really tries to remember what I've told him so he can impress me the next time he sees the video!
One night he had a dream that I we were at a party and I was getting really friendly with some blond guy. He woke up and told me he was mad at me because I was "all over some guy" in his dream. Then, he said
"the way you were looking at him and hanging on his every word, he might as well have been Bono!" I laughed so hard and I don't think I've ever loved him more than at that moment! He gets it!
He knows all about PLEBA and doesn't mind at all. He thinks the girls are hilarious and loves the pics of Elizabeth and the pants. He pretty much knows who everyone is and doesn't mind the "naughty" things that sometimes go on.
In other words, I am very, very lucky.
*edit for something I just remembered! We were on a day trip a few months ago, in a very rural area and for some reason, he pulled over and jumped out of the car with his camera. I looked over and saw that he was taking a picture of a street sign that said "Larry Lane." Then, all of the sudden, he came running back to car out of breath and when I asked what was wrong, he backed the car up and told me to look down at the base of the sign. He was standing next to a HUGE rattlesnake while he was taking the pictures
