I can't really vote, because none of them apply to me right now, but if they did, I think I would want it to be a mixture of one and two. I would love to have that person be like my best friend to where it didn't matter whether we were sitting home watching tv, hanging out together with friends, or traveling the world - I could always have fun with them, and make awesome memories. But I think it's important that couples have their own personal time too, and time with their separate friends. I know that when I am in a relationship, the time I spend with my partner is gold, but that doesn't mean I don't need time to just chill alone, or connect with my other friends. And the same goes from them. I think it's all about balance, and depends on the couple really. Some people love to be joined at the hip, and other's don't, so I suppose "to each their own"?
I dunno, maybe when I leave the single life and have more to report on, or that one guy finds me... then my answer might change, lol. Who knows.
