Is she sending me signals?

[SupMeing]

So there's this girl from my church choir who I'm having trouble reading.

She always smiles at me and laughs at any stupid thing I say. She used to stare at me a lot, but doesn't do it as much now that I've gotten to know her better. We talk every once in a while on Facebook, and they're usually pretty lengthy and fun conversations. (She told me once that she thinks our conversations are awesome.) But she really never asks me anything personal.

She only invites me to group activities, but every time that happens I'm like the only guy that shows up and I end up hanging out with her and a friend of hers. I don't know if its just coincidence or something she planned. (she says everybody else cancelled, and i do believe her.)

I've been taking it as a friends only kind of thing, because she'll stop talking to me for like a week or 2 and then suddenly be interested in hanging out and talking again, but these hang outs are only group hang outs.

She also seems physically reserved sometimes, as in she doesn't always greet me with a hug, but i don't know if it's because she doesn't like me in that way, or if it's because she's kind of shy.

What really confused me though was that a couple of days ago I was talking to her on Facebook, and we got into the subject of relationships. She started telling me that she has a thing for chubby guys, and that she would take personality over good looks any day, and how she's not into pretty boys. Then she started telling me about all these good looking dudes that she's turned down because she didn't like their personalities.

I myself am a chubby guy, I'm not the greatest looking, and I have a decent personality. I don't know if she's trying to tell me something here, or if I'm just imagining this.

What do you guys think???
