Is it coo for my mate to have new female friends knowing he have a partner?

its getting a lil frustrating that his new friends of his txting him "why you acting phony" "when are you going to have time for meeeee" just because he tryna build a fan base as he say but chopping it up hard with these new friends of his he tells me nothing wrong with having female friends but to me I think its a no no.... he says i have some trust issues okay! alright! "since its coo to have freinds knowing you have a partner tonight hes opening with Jeremiah @ the sky lounge and imma be lookin hot so why not have friends also???? And no SMIGGZ did not make it yet in the industry he trying to get there but see @ the same time I dont want to be no ones foo .... I mean I know its a say so on this right? I mean is it?
