<human>: Could you distill the essence of the text into 1-3 sentences?

Let me preface this by saying that I don't have problems with homosexuality. I don't care if you're guy, girl or whatever- you do NOT get to make passes at my guy! I can't tell if my boyfriend is oblivious, if he likes the attention or what. For simplicity's sake, we'll call his gay friend B. B will send my boyfriend like 20 unsolicited messages a day- messages that are very clearly not platonic. B will say things like "thinking of you :*" "we should definitely hang out more ;)" "**what are you wearing?**" What the actual fuck?  I was going through my boyfriend's instagram photos last night and B has liked and commented on **every single photo.** It's disturbing. Sometimes my boyfriend will post workout photos to whore for likes or whatever and B is always the first comment with some awkward emoticon shit. Yesterday my boyfriend and I were clubbing and I swear to god I saw B trying to follow us.

Do I go to my boyfriend with this? I've been paying attention to B for a few weeks now and I am positive B is sexually interested in my boyfriend. My boyfriend has problems with checking his text messages so he will only reply to like 4 of B's messages a week but I know he reads at least half of them. B and my boyfriend aren't super close friends or anything. However, they do have the same friend groups. In my ideal world, my boyfriend would cut B out of his life (block him on whatever) and I wouldn't have to worry about any of this.  I don't know if it's OK for me to ask my boyfriend to do that though. I've heard some horrific stories about girls coming between "bros". Am I in the right here? I have all of the passwords to my boyfriend's shit so I can post more messages if it helps. I know my boyfriend is objectively attractive physically but I am not ok with this random dude basically stalking him.
<bot>: BF's gay friend is giving me bad vibes. I don't know if asking him to cut that guy out of my BF's life is overstepping my place as his girlfriend.
