Fat experiences

It seems to me, you have to be pretty careful to avoid an embarrassing situation. She may already have a boyfriend, or she could be gay, or just not interested. Not all BBWs like being BBWs and may not like men who are attracted to fat.

So, I would try something very neutral until you get a better feel for the situation. Ideally it would be best just to catch her outside and strike up a conversation.

Good luck and keep us posted.

Start cooking stuff on the barbecue and pop your head over the fence and invite her over.

I would love an update here even if it's "I haven't really seen her."

The best thing to do right now is to just get to know her if you're interested in more. Start with simple side chat and see if she might be interested in heading to a movie or something.
