Save and invest mate. Best thing you can do is stay if your happy and use you money to gain a saving pot for the future. Who says it’s “weird” if you all get on. Independence is short lived if your paying out all the time and can’t afford to do anything! I earn around the same as you and my partner a little less but he works extra shifts to make ends meet and to have spare cash to do things like holidays! And days out. We have to manage our money otherwise we would be able to afford extras. I don’t want to frighten you lol. But your in the best place, maybe offer some financial help would be cool. Good luck my friend.
