I think my girlfriend is trying to fatten me up?

This sounds really strange, but I’ve been dating this girl for about three months, and about a month ago, she told me she was a chubby chaser. I didn’t really care at the time, and I am a skinny guy, but recently, she’s been trying to get me to eat a bunch of sweets and candy and stuff. I can’t tell if she’s being affectionate, or if she’s trying to fatten me up. I don’t know what to do…
