So I noticed my boyfriend was talking to a co worker of ours and being really sweet and affectionate (for him at least) and then he comes to me later in the day and is not nearly as nice, sweet or loving to me as he was to her. Maybe I'm overreacting but I'm kinda upset about it. He won't say more than two word to his own girlfriend but he will act way different to the new girl at work. Maybe I'm just emotional but in kinda upset over it. What should I say to him?
