<human>: So, my boyfriend told me the other day that he seriously considering leaving me to explore a relationship with a guy he had recently met. I guess the guy made a move on him (which was rejected) and essentially told my BF that he couldn't just be friends, it was a relationship or nothing. My boyfriend considered it and chose our relationship over pursuing a relationship with him. It crushed me that he considered leaving me for this guy and almost threw away something I feel is so special. But he chose me, so now we're building us back up. My boyfriend and the other guy went NC for about a week and in this time my boyfriend was telling me that the other guy would also talk a lot of shit about me. My boyfriend would always take my side, but it's still upsetting that this guy would talk shit about me, someone he had never even met! But anyways, I've noticed this other guy posting on pictures my BF is posting on certain social media platforms and it's a bit upsetting. Then I noticed that he's now the 2nd most guy he snap chats (right under me). It makes me feel terrible because I just want this guy gone, and I want him to leave us alone. He's already tried to destroy my relationship and he's sneaking back and it pisses me off. If my BF let a friendship resume, I know I'd feel very insecure because it would feel like only a matter of time before he leaves me for the other guy. But, I'm not one to dictate my boyfriends friends. I never want to tell him who he can or cannot be friends with. Is it rereasonable for me to make an exception and ask my BF to go NC with this guy?

Provide a brief overview of the text.
<bot>: My boyfriend almost left me for another guy. It seems like they're getting back into contact with each other and it's making me feel insecure. Is it reasonable to ask my BF to go NC with this guy?
