Leaving for a month

So something I love to do is travel, my fiancé on the other hand does not. He’s not very spontaneous, but never will commit to trips planned in the future either. I travelled alone and with friends before we got together, but since being together (a bit over 2 years) whenever we travel we go together. But the most we’ve done is a weekend trip to visit one of his friends in a city 2 hours away. and that was like over a year ago at this point lol. We’re both busy with work and school so I haven’t had much time either, but I still like to try to plan a weekend away every few months to unwind and relax and enjoy my life.

Anyways, he won’t be free to travel at least until April, as he’s busy withwork and the school program he’s currently doing. He’s so occupied during the week, even though we live together we don’t have hardy any quality time. I do most the cooking, laundry, and cleaning to make it easier for him, but honestly guys I’m getting burnt out fast.

I found an opportunity to travel like I used to, to go and volunteer in South Africa for a month - we live in the US. I have the money (just enough), and honestly idk when I’d get another chance like this. Part of me thinks it’s the perfect time to go, as he’d have more time to focus on school and his goals, and I could go and follow my passions and take some time for me away.

But on the other hand, should I just stick it out, at least til he finishes school program and can travel together? If I leave he would have a lot to take care of himself, and I feel bad - but I pretty much feel like going home is my 3rd job these days. I’m like a maid/personal assistant. Thoughts?
