What things you got from your relationship and marriage do you cherish most? What do you think love and marriage means?

Hi guys. Thanks for your attention :)
I’m a 21-year old gay man in China. Young or naive( :( ) may I be, I start wondering this problem.
I’m well-educated and I think it’s okay to share money with your partner if you do love each other, but I don’t think one should expect to live on the money his/her partner gives him/her; maybe I don’t have absolutely strong or mature mind but I am trying to manage my own stuffs. I don’t think I need some one to comfort me about being gay or sth. and I don’t think this should be the only reason why two men keep a relationship.
Gay men are still in low-profiles in China, and I just wondered, what things you got from your relationship/marriage do you cherish most? What do you think love and marriage means? :)
Thank you guys :).
