Paying subsistent bills into a situation your not overly fond of in the first place is a mistake if you don't have roots, minimize and micro everything you can for a couple years before you even think about starting a family, maybe start a business, suffer a bit to save money, I don't even have internet at my house unless I start working from home again, just gonna cost me time if I get sucked into a video game, rather actually have to go out of my way to waste my time.
If you want to save money, start by allocating your time better.
