I'm not normally the romantic type. I do like a good romantic comedy, but honestly if any of that played out in real life, I think I would probably feel more uncomfortable than sentimental. But I do like some corny things occasionally.
For example.
I like calling BF my partner. I think it's a better title than BF, because BF sounds so temporary and sometimes kind of juvenile. The way I see it is, we've already started our life together even thought the means to get married aren't here yet, and "partner" illustrates that better in my head.
Also, an acquaintance at my school just got engaged. Along with the ring, her FI gave her a leather journal and he has a matching one. They're going to write letters to each other everyday and then exchange them on their wedding day. I think that is rather precious.
