I've been with my partner nearly 2 years. He still lives with his parents for various reasons, no issues there. We are mid twenties.
He has however started to stay at my house (rented) most nights (think he's been at mine about a month bar the last three nights due to work).
My question is, how long before I should bring up a conversation about contribution towards rent and bills? He already helps with food.
Just for reference, he is self employed and makes enough money but occasionally has a lot of outgoings due go the nature of his business. I am employed and easily pay my bills but do not earn more than DP.
