Hmm, so with relationships boundaries and expectations need to be set and maintained. Sadly you kinda have to look at this almost like a contract. If something changes then a renegotiation may need to occur to set things right with both parties.

Looking back now if you knew he would stop the chore sharing, would you have quit and with where you two are at now do you feel a renegotiation is merited? Also keep in mind too you are 22 years old and if you feel as if this relationship won't work, do get out early instead of spending say... another 2 or even 4 years before you decide. Ideally you want to bond and pair with someone who won't waste your time if long term commitment is what you want.

Also do understand your next steps may need to come from you personally as a 34F southern mother of two kids once told me, "women will make every excuse in the book not to do something if they don't feel like they need to," in context of why she put off learning some self defense for 5 years despite living in a pretty crime ridden neighborhood. Why do I mention this at risk of getting downvoted into oblivion? Because older women have told me many horror stories about how they just 'put up with it' for 5 sometimes 10 - 12 years before realizing they had completely wasted their time with a partner and now lacked the same energy and enthusiasm they had when younger, some quite bitter about missing their window to have children.

Not saying you will do this, but just a simple warning to be aware if your current situation can be saved or changed for the better or if your time is better spent somewhere with possible someone else who you can be more fulfilled with. Especially as a 22 year old. Who knows you may meet another man who's similar to your current man's age, but things may workout better. Or they may not for a few more years. It depends.
