She has been gaining weight and sick lately. I have not snooped in almost a month but I was like what the heck, this is weird. So I looked at their FB and what do you know, they recently both liked a pregnancy center.
Woah. Well I would say maybe you're reading too much into it, but gaining weight and sick coupled with that little revelation, wow. You don't know for sure and I agree with Kaizen on sitting tight and not confronting her, but I think you need to prepare yourself for that as a strong possibility and ask yourself what that means to you.
