Is this love?

I have not read the books at all but I have watched the last two movies. When I recently watched Mocking Jay part 1 it  left me very confused about Katniss. Though out the movie she is consistently screaming for PEETA PEETA PEETA...and not once do I remember her calling for her bf. Is she in love with Peeta? Was there a love triangle this whole time and I didn't notice? Is this just friendship? What is going on because she clearly was being disrespectful to her bf and if she does have a thing for Peeta when did that happen? I remember them having some special moments but some of those were forced..so......SOMEONE HELP CUS I'M LOST.
