Should I forgive?

Thursday: I'm not feeling well, & having a horible day. I go to lunch, and me & Franklin (my bf.) were eating at the same table like always. Every other day, my friend Jackie sits with us. :) Buuuut, i feel like he speaks to her more whenever she's at the table.
Already getting a little jealous, i had a feeling he was starting to like her.. Then, that same day, he ended up calling me "Jackie".... I got mad, but, he apologized. His excuse was; i was just talking to Jackie so i got your names mixed up... So, i ofcourse forgave him.

Friday: He sees that i'm still a bit upset, he can tell by my "body language"... So, he kept saying sorry.. I said i wasn't upset and i was fine. I smiled, and turned away.. He put his arms around me and said; "I just want my old Jackie back.." after that, i just walked out. The worst part is, Jackie wasn't even there with us this time... :/
