what is it with him?

Well without knowing more of the story I can only make the assumption that yes, there is some jealousy going on. Most men you run across will have problems with your guy friends untill they meet them and get to know them better. The best way to deal with this will more than likey be in trying to communicate with your friend rather than your boyfriend. Let him know that he needs to be extra careful around your boyfriend and try to make him feel at ease so that your boyfriend can build some trust in him. He probably wont like it that you want him to do this, but if he values your friendship, he will do it because he also wants you to be happy. There is clearly some tension in the situation and I hope that this helps!

i would say yes it was about you. Your bf is just protective over his territory, you are HIS gf and this john guy maybe trying to cut his grass. So what id do is talk to both of them and get to the bottom of this, id tell my bf how much i love him and let him know nothing will ever happen with this john guy becos you love him only. Then go to john and say that to him, tell him you love your bf and nothing will ever happen between the 2 of you so he needs to stop flirting with you.

1st of all honey, you should write your question more clearly, and learn how to spell better before submitting a question like that. I don’t mean to sound harsh, but it would be easier to answer your question. Ofcoarse they are jealous. You know how men are, and they probably fight in front of you to show off their manlyhood..I would have a sit down talk with your fiance and ask him if there is anything bothering him about your freind, and do the same with John, your friend. Try to clear up any misconceptions or jealousies that might be going on.
