<human>: Can you condense the text into a few key points?

Long story short, he has a friend who is female that after a fight and reading text messages I know he does have a thing for. And he has also told me he will just omit his friendship with her from conversations and sees nothing wrong with that. Well we had a blow up and got over it after lots of conversation but I still wonder.

Well now he has been reading my texts and noticed one from one of my friends who is male. I have made it very clear to my friend that I have a man and am not the kind of girl to cheat and almost all our conversations are very platonic other than the occasional time he throws a pick up line at me which I blow off with a "lol" 

Well now my man is upset that I have a friendship with a guy. Tried to get a fight started last night which I easily told him he was full of shit and pointed out why and it shut down the conversation and we went on to have a great night and this morning we were just fine to before he left for work.

I guess my
<bot>: is, is it OK to have a friend of the opposite sex while your in a relationship? My ex kind of screwed with my head on the subject.
