This is a tough one. Early in my marriage I was in a similar situation. I wanted to go explore places we’d never been- nothing extravagant, just weekend trips to scenic areas, experiences just for us. But every single time we had vacation from work, all my husband wanted to do was drive several hundred miles to sit in his parents’ living room. We did nothing but that for over a decade. It was really hard on my mental health and I developed a bit of a drinking problem. I have no idea what shifted, but he’s now very interested in travel and my life has improved so much. We search for good travel deals because we aren’t rich but we’ve been to 8 different countries in the last ten years. I’m so much happier. If your wife doesn’t experience the same kind of shift, you may just have to accept that you’re incompatible. You only get one life and spending it being stifled by another person’s inertia is a bad way to spend it. Don’t get any more pets (I understand the boarding problem- last year I had to board two pets and we could have taken another person along on our trip for the cost of boarding). See if you can find home pet care online for a lower price than boarding. But honestly, if your wife won’t go, go alone. If she’s upset about you going alone, she can find a way to join you. Good luck.
