See that's the problem. Either party can just quit at any time.
Get a house, couple kids and a retirement fund. Then have her watch sex in the city and have girls nights out. To divorce papers, child support, demestic abuse and losing your family.
Sounds great casually but let's be real here. Someone's heart will get broken eventually. Unless you're going to marry a God fearing feminine unicorn. You have to agree there's a large risk here.
Once you see your father, extended family and friends go through this pain. You can admit it isn't for everyone. Loneliness is less painful.
You can look at the bright side though. You as a man can do whatever you want. Focus on yourself instead. And spend all your own money.
