I'm really glad you told your H how you were feeling. That's a positive thing in a relationship to tell someone you would like to celebrate all the years you have been together. Could the two of you brainstorm together and think of something special to do to celebrate that doesn't involve going on a trip? Maybe it could just be going on a walk in a favorite area to see the scenery. And then stopping for lunch after at a favorite cafe. I think what's important is the urge to celebrate and mark the occasion, not necessarily to go someplace far away. You can do that later, as your husband said, when you have enough mileage accumulated. But please don't let that stop you from celebrating now. This could help the two of you draw closer.

It's understandable you would feel jealous of your T. I hope you won't let that feeling stop you from doing something with your H to mark the occasion, though.
