bf choosing friend over me am i right?

[lovelyone]

my bf and i have been together for 2years

he has a friend named carlos who is a player literally ive seen it with my own eyes. so anyways since i can remember carlos has told my bf that we need time apart, he is always inviteing my bf out without me. when they do go out he says things like why do you have to listen to her and be home at a certain time? why this? and why that? he has actually said that he doesnt invite my bf places because of me, well not me but because he has a girlfriend. then when my bf told him that i had become his fiancee this was carlos' reaction he gasped and said dont ever say that again. so i see all of this as that he doesnt want my bf and i to be together, that he wants him to be single just like he is and go out and about with him. when carlos says things like this i get mad and try to defend my relationship by saying that we love each other and we dont need to **** other people, or that we come home at certain times out of respect for each other and stuff like that BUT my bf just stands there. he tells me that he has told him to not say things like that in front of me and that i shouldnt listen to him that he's just talking out of his ass. but it bothers me that he wont stand up for out relationship. ive told him many times that if he loves me he should stand up for us but i think he's more afraid of losing his friend. that hurts me more than u knoe i mean i kind of understand but at the same time this guys is not a very good friend period. i mean if he were a true friend wouldnt he just be happy for him? why would he straight up tell him that he doesnt invite him places because he has a girlfriend. then when my bf calls him he never picks up or calls him back but if but he calls my bf younger nephew to go out. isnt that wrong? why is my bf wlling to keep a guy as a friend if he doesnt respect me, our relationship or even him.he's been friends with him for like 8 years i dont want my bf to resent me for losing a friend but is it possible that maybe he should lose his friendship. someone please tell me AM I RIGHT FOR ASKING HIM TO STAND UP FOR US AND IF HIS FRIEND DOESNT STOP SHOULD THEY STOP BEING FRIENDS?
