<human>: I have had a close relationship with my friend for over three years now and we haven't dated in two years and we are both in committed relationships now. I had asked my boyfriend (who I've been with for less than 8 months), if it bothered him before and he always said no, but now out of the blue he wants me to stop talking to my friend completely. My boyfriend says that it hurts him when I talk to my friend because I should be able to talk about everything with him, but I mostly talk about stuff I have in common with my friend like books/movies/activities which my boyfriend has no interest in. I'm very shy and introverted so it's not like I have a huge group of friends, just three really close guy friends (one's gay, one's practically my brother and the other is my ex), so losing a friend is kind of a big deal to me. I know I have issues with thinking people are trying to control me--but this really feels like he's trying to control me and I feel like he could turn on any of my other friends too...Obviously I don't want to break up with my boyfriend, but I don't want to lose one of my best friends either. Any advice reddit?? (sorry for the wall of text)

Can you condense the text into three sentences or less?
