Dear Cautious: Early twenty-something relationships have a high failure rate. Still, given that you two have put four years into your relationship, I think it's more than reasonable for you and Don to have certain expectations at this stage of your relationship, and so do you. Now is the time to clarify what these are. What are Don's future plans? What are yours? Are you roommates, lovers or both?
If he agrees with you that this moving in may mean marriage in the future, then the “I pay the bills” line is an unfair card for him to play because he knows the limitations of your current situation. If the plan is for you to pay for part of the expenses later on when you have finished school, come to an understanding about that now. Clear expectations lead to fewer misunderstandings later on. Good things are possible when you both play by the same rules.
