Was I out of line????

Well, I guess it would be good to know why it exactly made you pissed that he had a girlfriend already. Did you want to have exclusive rights over who he had sex with? If so, that's fine, but except for STD concerns only a girlfriend/wife should have those rights imo. Myself, I wouldn't expect those from a girl I was seeing unless we had this understanding of her being my girlfriend (and vice versa) and not just a girl I eat dinner with a couple times a month.
