I don't like the word "lover", personally. In the contexts in which I've heard it, it seems to have an illicit or turgid meaning that I don't really want to convey when I talk about my partner.
I tend to use the word "partner" in writing, and P's name when talking to people. I'll use "boyfriend" as well, but the term grates on me, since I personally feel a bit high-schoolish using it.
