Hello beauties!

I am single and recently bought my first home. After this purchase I really started seeing men as more of a liability than ever before, but I’ll save that for another time haha. My question to you all is: if you own your own place and then get into a relationship with/marry a man, how do you divide the bills? I don’t want him having any stake in my home (hello prenup) but there’s no way he’s going to live for free. Curious how you ladies work that out.
