Regardless of orientation, when someone has had an awesome relationship for years, somehow you feel like deepening the commitment you already have through the ceremony of marriage. Ceremonies do have some meaning in terms of giving a sense of seriousness about finally tying the knot with someone. My bf thinks marriage is a stupid legal thing and its just a way out for the insecure. I dont agree. Things change after marriage. You may be nearly sharing just about everything, including finances during a live-in but admit it, it just doesnt give you the same feeling when you share eachother's surnames, introduce eachother as spouses. you feel like 'yes, he/she is the only one for and i am not afraid to let the world know we belong..which means that xyz cant go around sleeping or making out with others!" plus, once i get married, no worries about wrong time pregnancies! So marriage is good!
