Although I am not married in the legal sense, I consider myself married, because me and my SO have known each other for 4 years now, and dated for at least 1 or 2....and I currently wear their ring around my neck. It's not an official engagement ring or anything, but I consider myself married simply because I have no desire to not consider myself in that way. With this being said, no we don't have sex, live together or anything like that....but we're both comitted to each other, in love and very happy. Eventually, we know we'll be together, but as for right now, we're content to finish schooling, start our careers, and then marry.
With that said. It is very important to me that I wear the ring they gave me. They wanted me to wear it for a special reason, and I refuse to deny their gift. I love them, and that is very important. I think, that more than anything, it helps me, because it reminds me when I get sad about all of our friends being married/engaged while in college, i can just grab my ring and hold on for awhile. It's a nice reminder, and instantly, I'm so thankful that I have them.
