The compromises your lover makes in order to be in this relationship with you probably means that they have to divert themselves from the things they really want to do in life. It isn't that you make demands on them or their time; far from it. It's just that sometimes this relationship with you is not conducive to something else they'd like to pursue.
Maybe they wish they could travel more or move to a different state or country; but if they leave the country, they know they'll lose you. This is the type of problem you two face. You have a strong hold over each other, and you might not want to follow your own natural path if it means moving away from each other. But if you don't follow your dreams because the relationship is holding you back, you're actually doing yourselves and each other a disservice. Finding your way in life doesn't have to mean the end of the relationship, but it may mean making a lot of room for each other to be the people you truly are. You each might end up putting up with situations that make you very uncomfortable, even insecure, and that could be quite frustrating for both of you. It's up to you to decide whether the good things you get out of the relationship are worth the frustrations it also provokes.
