WELL... You will most likely have to put those $$ meals aside unless it's just you and dh (though you could get away with a baby/toddler for free for a bit). Our family eats a lot simpler and cheaper
I am not sure how long you have been with your SO, but my dh & I dated for 4 years before we got married and then were married for almost 5 years before our first baby arrived. We did a ton of pricey meals and extravagant travel before kids so we were ready to 'sacrifice' and welcome a little one. I never regret my kids but life does change when they enter the picture. It's ok though cause change is good and the change children bring isn't like anything else. It's mind-blowing really how much 'change' one little person can cause lol. They leave footprints on your heart for real...nothing at Disney could ever compare to what having your own child brings into your life.
Having said that, I don't think everyone has to have children to have a fulfilled life. My dh & I are both only children (and he is only grandchild) and we both felt rather lonely growing up so our desire was to surround ourselves with a large family. I know you have siblings (not sure on your SO) but you could feel you are surrounded by family without needing to have kids...? Having kids can give you purpose though that I'm not sure siblings can.
It's such a personal decision! You still seem really young to me so just enjoy life for now. You'll know when it's time (or not time). I was 23 and never having kids. A year later, I was pregnant (on purpose) and couldn't wait to be a mom
