Relationship obligations?

I am a man and just wondering what women feel relationships entail?? Men too? What does it mean to be in a relationship? What do  you think as a partner you are responsible for? For me (married for almost a year) I feel that partners are meant to support, believe and unconditionally love their partner. Your partner should feel wanted, needed and supported on a regular basis. Intamacy is very important  as well.. What are your views on sex and physical aspects of being with someone.. Just looking for other people's views and takes. Thanks!
